It's still possible that they are wrong/bad actors; but that can't be determined based simply on a single change of opinion.
The fact that people still believe "scientists" after all those flip-flops is astounding. It's like those "scientists" believe their reputation (individual and as a group) is invincible and they can get away with making unsubstantiated claims without being called out -- and surprisingly that's exactly what happens, mostly.
I'm not "anti-science" by any means and I don't believe in "conspiracy theories" but I can see why people are starting to view the scientific establishment with suspicion.
