Twitter is explicitly communicating that dead celebrities have actively subscribed (paid $8/month) and verified a phone number, which is just inaccurate. At the least, they should have just left the legacy copy, because this is tasteless.
I'm not convinced this is tasteless - dead celebrities may still have people that manage their affairs and accounts, and they could have subscribed. I know that doesn't cover all cases, but I think the journalism of this article is at least poor and doesn't consider all cases.
It feels ghoulish because it doesnt read as something done for their memory but something done using their memory.
