Difficulty was not the reason why it took so long. The excuse has been that they want tweets to be immutable, so you don’t share a tweet for it to be changed later.
* Do you reset the likes / retweets after an edit? If not, what happens if folks start selling the ‘edit’ on viral tweets?
* What happens if the original tweet violates the TOS but then the edited version does not? Does the original tweet in violation still get persisted? Does the edit get persisted?
You’re onto something. I’m pretty sure that’s going to happen if edits are not limited. We already see “wow this went viral, here’s a link to my album”
