This isn't only ongoing, this is by design, and being actively pushed further, because in the EU if you are by definition an equal opportunity tax haven like Luxemburg you are golden.

Luxembourg is like the delaware of Europe, it's a banking and financial institution state and both its own laws and the EU laws and policies it lobbies (and when you effectively are not only Delaware but also the DC of the EU it kinda helps) for ensure that it would continue to operate as one.

The bad thing that Ireland and is a big no-no in the EU is to go to the likes of apple and say:

Hai Apple I really want you inside of me!
I know I'm small, and I don't have a huge workforce and internal market, I'm not like Germany.
I also don't have a huge economic and financial infrastructure like Luxembourg, Switzerland or UK (London) but I'm a really hard worker!
Tell me what skills you need, and I'll educate my people, I'll give you low interest loans to build your shiny offices and I will give you tax deduction if you employ my peeps.
I would do all that I can to make sure it will be easy for you to operate here because I really don't have much to offer and I need to compete with the bigger countries since the euro is expensive and the price stability is managed by the ECB and my people need to eat and loans I've been taking on are becoming harder and harder to pay.

Now this is the only way that Ireland can really attract large corporations and make it more lucrative to invest in its industry, this is what effectively every country on the planet does when it wants to grow.
And since Ireland can't control it's own monetary policy and currency it also can't just be a cheap place to be, while there is some local variation because of the mandate of the ECB to control the price stability within the Eurozone the prices of many goods and services are quite similar (Ireland is actually more expensive than Germany because it's an island which increases the costs of logistics and it has lower production which means more imports which add costs even if they import within the EU) it needs boost its economy in order to match the salary level of the other Eurozone states and to do it it needs to offer something to corporations.

It can't offer them a huge workforce because it doesn't have one, It can't offer them access to financial and banking infrastructure because it doesn't have that either, what it can offer is English, fund both academic and vocational education and training based on the skills those companies need and give them tax incentives to come and employ Irish people.
Ireland isn't Luxembourg Apple didn't set up effectively a "shell" there that's pretty much there for easy tax loopholes and actually employes no one, Apple employees directly over 6000 people in Ireland and indirectly 4-5K more, same goes for Microsoft, Google, Facebook, Amazon and the likes.
This isn't some tax break Island that those companies incorporate in by name only and don't actually have staff, companies have "real" employees in Ireland because the Irish "incentives" are tied to direct employment.
Ireland isn't trying to create tax loopholes to make a quick buck to split it between a few 100's residents, it tries to keep it's 5M people employed, forcing them to play by the "same rules" as 4 of the world's 10 largest economies is asinine.
