Of course they could abandon all pretenses and just call it "ticked" accounts without saying what it means at all...
Your case would imply there is a confirmation interval... which I don’t think is the case.
YouTube's check mark is a tiny unassuming grey thing, and they're going through the exact same process right now where they claim it's being construed as an endorsement.
I researched this for the 2018 Reverse Hackathon run by HackMentalHealth and found that in 2015, approximately 0.05% of Twitter accounts were verified (source: https://medium.com/@Haje/who-are-twitter-s-verified-users-af...). The source above has an even deeper breakdown on the verified users' backgrounds.
If they don't want it to be construed as an endorsement, they could let any user not only apply for verification, but actually verify their identity behind their accounts. Not force, but allow it. This could shift the percentage of verified accounts up to the point where they're not part of an exclusive 0.05% club.
If they keep at it 0.05% of the accounts that they deem to be worthy of being verified, then it sure seems like an intentional endorsement.
(my article: https://medium.com/hackmentalhealth/why-twitter-should-verif...)
I think making it a brand-coloured tick conveyed too much of a positive message so people took it as an endorsement, leading to pressure to "unverify" if that person did or said something bad.
Given that action, the "verified" tick then becomes an even stronger signal of endorsement.
Perhaps it would be better to call them "Partners" like on Twitch and make it an explicit contract with revenue kickback.
