I'm aware of what the FSF is. Downvoting me because I posted free-as-in-beer alternatives that aren't open source is childish. They're valid alternatives for people that don't want to use zoom and entirely relevant to the conversation.
It's as though the title was "Try these green ways to generate energy" and you responded with a list of petrol engines which are painted green. It's not wrong, it's not unhelpful, per se, but does somewhat miss the point.
OP's post is about choosing free software alternatives in place of proprietary software that abuses your rights. You recommending more proprietary software is entirely against what the FSF's article is saying.
