There's nothing the GPL tries to cross, that's exactly what that quote means in general society as well.
For example, you're free to wear the same shoes you do outside in your own house, but if you're coming into my own house, I have the freedom to require you not to do that.
The GPL does the same.
And yes, you're free to refrain from visiting my house if you disagree with what I am asking of you, same as you're free to not use GPL code and therefore not abide by its requirements.
The only thing you are not free to do is come to my house and ignore my rules, likewise use GPL code and ignore the GPL. That's it.

Couldn't agree with you more, but Microsoft and other proprietary software makers have the same right (to dictate what people can do with their software). For some reason, GNU believes (as RMS has stated in various talks) that not sharing software is immoral.Now, is not sharing software immoral because (1) it can be copied at no cost, or (2) because you can't morally tell people what to do with the bits once they have a copy of it ?
(1) is nonsense because creating the software has a cost, and anyway, just because something was free to you doesn't mean you can't charge others for it.
(2) is contradicted by the GPL if it tells you what you can do with the bits after you have them.
You can make the argument that free software results in higher quality software, but it's wrong to make a case for it morally as GNU does.
As for immorality, you can read the justifications here starting from item 4 (Voices from the Revolution): https://www.drdobbs.com/the-ethics-of-free-software/18441458...
> GPL never says you can't charge for software.
My point is not that the GPL is contradicting itself, but that the GNU philosophy contradicts the GPL.There is a quote in item 4 at that link you shared, which says:
> I think that to try to own knowledge, to try to
> control whether people are allowed to use it, or
> to try to stop other people from sharing it, is
> sabotage.
Putting a paywall up is a method of control. I think I represented GNU's position fairly.The only thing you're not allowed to do is do a change and "close" it.
It's like you're begrudging freedom fighters their actions because they are violating the feudal rights of their historical oppressors.
