Well, .com-bubble came and went, but mind the settings.

Yes, nowadays, new buildings in every larger city come with gigabit ethernet wiring and several ISPs' fiber connected to the basement switches as standard. Older flats (pre-revolution era, before 1989) have FTTH GPON from two or three providers. Really historical buildings have at least DOCSIS 3.0 or VDSL. That's the physical layer. You can get 100 mbps/300 mbps internet (depending on where you are and how lucky you are) for about 20 eur/month, no data limit.

But that came for the price of very slow starts. After the fall of the socialist ("communist") government in 1989, there was:

a) chaos everywhere, many large companies (in the "common domain" beforehand) and employers of many workers were fraudulently privatized to the hands of few con-masters only to be turned into quick cash through sellouts, or just to be defrauded primitively (literally: 1. have a political friend, 2. privatize for one crown, 3. withdraw cash [millions to billions of crowns] from all bank accounts, 4. let it go bankrupt).
You could buy and carry firearms no questions asked (nowadays we still have more reasonable firearm laws than the rest of the Europe, even some form of Castle Doctrine - in Europe!! - but now you at least have to go through psychological and firearm test and you cannot be a convict -> didn't matter in 1990's and even worse, there were global amnesties, even applied to serious criminals, because "communist" judges must be wrong, so let's release everyone from the prisons - and those few not released revolted so hard, army had to be called in).
One day you could be a common Joe, the next day you are a multimillionaire via privatization through a friend in politics. Or you may be a common Joe going about your common life and while returning home from work, a car or phone booth next to you explodes, because one mafia group was paying debts to another...

b) high demand for foreign goods and low wages relative to foreign currencies. Imagine buying a 486 computer for 100.000 crowns, whereas your monthly wage is 4000 crowns... Would you pay your two years income for a computer?

c) missing voice/data infrastructure (power, water, gas was fine, it was fine well enough to be defrauded without any investment for many many years ;) ). Well into 1990's, you still had to be on a waiting list for... a phone line.

So, in 1999, we had a high school field trip to the offices of telephone company, to be shown a 56k dial-up internet shared across 10 or so computers there. A year later, the whole school (20 old computers in one room) was wired through one 56k and we were loading, line by line, new screenshots from the upcoming Red Alert 2: Yuri's Revenge.

Well, you could get dial-up at home, for around 1% of your monthly wage PER HOUR... Many of us, the luckiest ones, actually got the dial-up after 2000 and were given the limit (by parents already strapped for cash) of 1 hour internet a day.

While I cannot comment about the accuracy of the takeovers from the OP's article (I was in the high school after all and was offline fiddling with the expensive LPT scanner, not watching politics), and there always are hidden agendas and components to the story; just to summarize, in those days:

a) nobody cared about the .com-bubble, the internets were a very expensive gimmick to download as many Pascal tutorials and early-media (game reviews mostly) content as fast as you can on a time-metered connection, typically not originating from the .sk TLD,

b) many large companies, say machine industries or water mains, with all their assets were privatized and brought to insolvency on monthly basis (from that era, "privatization" is still used as a curse word with negative connotation).

The answer to the question why government didn't take over the TLD by force unilaterally - simply, the first governments cared about defrauding as much as they could, and the next governments cared about being viewed as the "right" alternative to the previous ones, while trying to defraud all what was the left with less media exposure.

And finally, when some wise heads finally came to the realization what the internet has become worldwide and will become nation-wide, we were already in the middle of accession negotiations to become an EU member, implementing required laws. That may be the final answer to your question:

- the defraudation was done in the "wild west" years of 1990's after the revolution,

- while the "repair" had to be done under the strict international-grade laws and you simply can't take it unilaterally back...

I don't want this to sound overly negative, it was fun years. For example, I, being born in the 80's era still experienced in my late 90's teens: 8-bit era, 16-bits and finally 32-bits, as they got to us belatedly in 90's. People, being fed up with slow, time-metered and monopolised 56k even in 2000s, started popping up amateur 2.4 GHz networks everywhere, even on remote villages, and that in turn, with "real" ISPs seeing they would get nowhere with lesser service offering no advantages over a next-door high school students' wifis, has lead us to the FTTH/FTTB paradise we have nowadays. We also skipped the ISDN entirely (although it was available). There was time-metered 56k, flash, flat-rate 56k and wifis everywhere, flash, ADSL, flash, fiber. The fast 8-bit/16-bit/32-bit transformation experienced in one's youth lead us to many world-grade startups and companies for the country with the population count of one larger capital.

Just wanted to say that 90's were dark in Central Europe and things more life-important than a TLD had changed hands then...
