Nah, bitwarden is just that common as a choice. Literally everyone I know offline that uses a password manager uses it.

I'm not saying there isn't astroturfing involved overall, but it is a very popular service, so don't be surprised when there's plenty of real people too lol

Tbh, it's also the easiest imo. I even got my mom using it because it took five minutes to get going, and hasn't given her a single hassle.
