> So, after all, it's my fault that maintainers abandon ports, because no one appreciates their work, including me?

No. It is not your fault that maintainers eventually decide to move on. It is nobody's fault. In fact, many maintainers do work in spite of the fact nobody appreciates it. In some cases, it's even a good or great thing to move on -- maintenance is time consuming and there are many other valuable things to do in life, as opposed to writing software, or even simply working on software you think is more important.

But it is your fault for making shitty posts like a child on the internet, in attempts to allude that Debian, somehow, is just fucking around with you personally or something -- or that they do not have any rhyme or reason to their decisions to do things like this. Your post might as well have read "why not just get rid of ARM too lulzzzzz amirite guise?!?!?? debian is so dum", like a 4chan pepe meme regurgitator -- and it would have had the same amount of content. It's simply extremely ungrateful to people who have put in 10 years of work on the PPC port already, probably much of it their spare time, to act this way.

Nobody is maintaining the port anymore. That's unfortunate if you depended on it. I've been burned by lack of maintenance too. But, here -- it is not a conspiracy against the hardware or an affront to you individually. It's just the reality of the fact nobody wants to support it anymore, and the involved people are moving on. You need to accept that. There's no blame on anyone. It's simply the way it is.

The reason you're getting responses that are effectively just brushing you aside, FWIW, is because many people here are involved with or have maintained FOSS to a large degree, software that is diverse, that has been used by many people, and in many contexts. That includes me. Unfortunately, a large part of that territory involves dealing with ungrateful users like yourself, who not only do not understand how such projects tend to function or operate -- but also who interpret choices they dislike as personal attacks, and furthermore contribute nothing of value on their own, or even allege that the motivations behind some decisions are unsound (while, again, having no insight or ability to contribute meaningfully). And I don't mean code. Most users rarely even, if ever, say "thanks". I don't write free code to get thanks, I don't assume it. I do try to assume that when I write code, I won't be treated like shit from ungrateful nobodies.

And, as unfortunate as it is, and however much it pains me to say this directly to you -- experience is telling me that, right now frankly, you are just another ungrateful, whiny user who is unlikely to contribute anything of value or substance. And despite the potential possibility that you could contribute things of value, after extensive work -- it's really not in my interests to "work towards" accepting attitudes like yours. There are 10,000 people who are at least 10x as qualified you while being nowhere near as annoying. I can wait for those people. Hell, I'd rather wait for people who are 1/4th as skilled as you and less annoying. At least I'd have the opportunity to mentor or help someone who isn't going to accuse me of bad faith every other decision.

Putting up with people like you does not make me any more excited to write or maintain my software, it makes me less excited. This isn't a happy thing to say. But it is the world we live in, and I have better things to do than appease users who act like brats.

You'll get less agitated responses if you drop the malicious implicit assumption that Debian or whatever is doing this to spite you, or that people are responding negatively to you are just doing so to troll you because "they can't understand your side".
