And is illegal.

I just read this as: "Separate program needed to make up for shortcomings of flatpak!" This is to be lamented, not celebrated.

Is it actually better?

No idea, I don't use either. I don't even know what you mean by "better" in this context.

I have a spare room in my house sat idle 80% of the time. I could easily install a few racks of servers in there and have some gigaflops of computing power to contribute.

But actually, being "idle" isn't the same thing as "spare" because it would cost a lot of money to install racks of servers, just as it costs money to run computations on an otherwise idle computer.

So I mean no, but no. It's only spare capacity in a stupid, convoluted way that's disconnected from common sense and common usage of the word.

But you managed to brag about having hundreds of gigaflops of taxpayer-funded computing at your fingertips so good for you, you go for that validation from strangers on the Internet.

I hate how much of a monopoly they have in the space

For now, until economics catches up with you :-) Enjoy it while it lasts I suppose.

would rather use some electricity to support a good cause than have the computing power sit there idle.

That's not "spare" though. That's my point.

What do you mean by "spare"? Modern CPUs scale their electricity usage according to utilisation.

GPUs

In English in England, that sentence reads as meaning all Imagination GPUs. Were it less than all GPUs, one would expect "Some Imagination GPUs" or some other qualification.

The contrast between the two forms gives the impression of deceptive marketing. And that's what it is.

Bullshit. There are tons if Imagination GPUs with no free software driver.
