Crazy how the people who believe the government planned the pandemic are also on the side of the guy who ran the government at the time.

Under plurality voting, third parties are objectively bad for the winning chances of whatever party they pull more voters from (and/or bad for whatever major party you personally would vote for, if you personally vote third party). That might be what some people meant by them being “bad”, even though they prefer one of those major parties to win (and cheer on anything that makes the other party less likely to win). Although it’s certainly possible that some people just think they are bad in general. People do have different opinions, after all.

It’s only hypocrisy if they do things that disagree with their own views, and their own views are internally conistent in this case. Their view is not that all third parties are bad, their view is that third parties that have a negative impact are bad. So it doesn’t make it hypocrisy just because it disagrees with your straw man of their views.
