To be honest I would have preferred the limited editing, as it can hold people accountable for their actions. Say someone says some really horrible things, but has the ability to alter this at any point in time, do you find this to be fair?
We cannot always undue the harm that words can create, why should you be able to go back and change those words far into the future?
Someone made a valid point in a previous contest I held about this very topic. Since posts at the time were limited to editing only to the first week, a lot of people who used racism, hate speech, etc. would be held accountable for it as it was eternal on the blockchain. This allowed any potential future employer or person to be able to possibly find these posts, and see who this person is behind a screen. Giving users like that the ability to alter their words in the future without limitation is basically granting users the right to censor their own selves at any given time.
