I generally agree with fighting corporate abuse, though IMO, GPLv3's anti-tivoization clause is kind of misguided. It may stop locked-down hardware makers from using your software, but it doesn't stop the hardware from being locked-down in the first place.

We have evidence that any hardware maker that would open up their hardware will do it already (see: reMarkable, Ubiquiti offering SSH root access). If you try to fight that battle by holding software from them, you only lose them as a contributor as they make their own, which is worse for everyone.
