I don’t know. If my parent was an Astronaut and they decided to stop being an Astronaut for me. I would hate that, feels like a burden.

Math and physics (or any subject that requires calculation) usually requires practice. Applying the knowledge in a short timeframe is different skillset then just having the knowledge.

That only applies if you modify/distribute it. That doesn’t apply to a user. I guess comparing the length of a company’s employee handbook would be a fair comparison to the GPLv2.

Yea, if someone is down on their luck or struggling with addiction. Pretty sure selling a gun is a step before losing a home.
