What's wrong with proprietary software? Also, I'm not fond of his philosophy when it comes to programming. Not minimalist enough. Everything is bloated.
I used to think he was too extremist, not anymore since the situation is getting worse and worse as he warned. For example a lot of commercial software now calls home to ask for authorization to be run.
Also I cry every time I have to waste half an hour poking with an disassembler at some piece of shit that artificially doesn't want to let me do something. That's just sad.
The real problem is that people in general don't give a shit about freedom, they just care about convenience / instant gratification. That includes me: as soon as it's cracked it's all good. That's road to ruin for sure.
