>> And no, none of the folks I'm thinking of actually make money from password management solutions.
Not directly, but maybe their peers do. If your buddy works at Facebook, you're not going to say bad things about Facebook's business. It also applies to some extent if it's your friend's friend; group-think is a powerful effect.
>> Your comment sounds the same as "of course all those doctors would recommend getting vaccinated since they make a profit from selling you the vaccines".
Well of course that's a factor to consider. The medical industry is not immune to ulterior motives. For example, doctors have been known for over-prescribing opioids and many people actually died as a result. I'm pretty sure all these doctors thought they were doing the right thing; all their colleagues were also prescribing the same drugs.
Also many drugs which received FDA approval were later found to be unsafe, caused birth defects, deaths etc... It's foolish to suggest that anything is 100% safe and ulterior motives will certainly have a negative effect on safety.
