It's not absurd at all. People who buy Nvidia cards to use with Linux are actively supporting a shitty company that is causing them problems.

Not helping them and recommending they return or sell those cards is turning the tide against the company, regardless of how small.

This is not about "ideologies" or "being kind", this is about improving the situation for everyone.

We should not work to pick up the pieces for a shitty company that doesn't want to support us, we should encourage people to buy from companies that do, because that will improve things for everyone.
