Valve just takes 10% more than everyone else

What do you mean? 30% is used by almost every digital store.

Because that leads to the degradation of the software? Or because they provide most of the valid feedback? Or because that would help more users become more advanced?

This makes it sound like non-political violence is acceptable...

You said there are too many stupid users, then you said the software has to suit them. I see this as a problem when software targets stupid users because then the rest suffer from it being less convenient for them.

Also I think it's hilarious how things become more complex for developers who should actually have the power to fork things in order to make them more suitable for advanced users. And apple is a good example of that. I would be a huge iphone fan if it wasn't a walled garden in software terms.

Just wondering would it be any better if he was shot dead?

I know. This is not about how dumb users are, it's about how dumb the software becomes with time.

I think most things in browsers got degraded thanks to Google, but also due to that specific way of thinking.

That's not an opinion. That's the lack of it. Plus a few grams of whataboutism. You're a victim of Russian propaganda agents.

For example? How do you do that with terrorists?
