Because people who vote Stein at least in theory should be ideologically-aligned with Democrats than Republicans. If you’re voting Stein because you are on the left side of the spectrum, then you need to educate yourself that this is a wasted spoil vote that only enables the Republican party candidate who is further from your goals to get in power. Green party candidates are often bankrolled by Republicans. Guess why.

Ideally, we’d want life-long Republicans to not vote or vote Kennedy or West while we want Stein voters to vote Biden.

Moreover within this community that is predominantly left-leaning, the message is: not-voting or voting third-party helps Trump. If I was in a conservative community, sure I’d be pushing for apathy and voting third party.

Now you know what right-wing operatives and online troll farms do.
