I would say that people can change opinion as time goes by. The key is to have a logic and motivation behind the switching. A solid one.

I wouldn't criminalize the fact of 'changing idea' about something: I changed my idea about Bitcoin a ton of times as my knowledge of the protocol increased. Every bitcoiner had more or less the same journey.

Michael Saylor changed idea, Satoshi Nakamoto changed a lot of his/her ideas (for example about Bitcoin scalability, blocksize ecc), Adam Back changed his ideas.

I mean, changing idea is not the problem.
