This is exactly how science is supposed to work. People learn some new things and they update their opinions based on that new data. That's a good thing.
The idea that people aren't allowed 'second thoughts' is probably the worst thing to happen to general discourse.

Only they can answer that. The general point is that people should be able to change their mind; and the argument that 'you used to believe something different therefore you must be wrong/acting in bad faith' is nonsense.
It's still possible that they are wrong/bad actors; but that can't be determined based simply on a single change of opinion.
