The check marks only briefly indicated "trust". By the end of Twitter's public domain "bluecheck" was used as an insult against self-important posters that had gotten approval from the Twitter regime, because that is all the marks were good for. You had accounts of high-impact people go unverified despite hundreds of thousands of followers because they were not in alignment with Twitter's progressive values. This is evidenced by the fact that Twitter would, repeatedly, use the revocation of verified status as a form of moderation against people, as if bad behavior suddenly made an account not who it claimed to be.
