I don't know. I think this is what they WANT you to think, honestly. This may have been the case 5 years ago, but from my anecdotal evidence of just asking around friends, family, co-workers, etc. this isn't really the reality anymore. Most of who I have talked about this with find it old, dated, and full of re-posts/spam. I would be curious to see their actual numbers on ACTIVE users, minus their terrible dark patterns to "get" users.

Pinterest's S-1 filing[0] on March 22 2019 says their MAU (monthly active users) is ~265 million. It also says the WAU (weekly active users) is 57% of MAU so ~151 million Pinterest accounts log in at least once a week.
Of course, the Pinterest executives could falsify that information on the S-1 to mislead and hype up the IPO but that carries the risk of the SEC slamming them with fraud and the DOJ pursuing criminal charges.
