He'd probably get in trouble with the EU GDPR data protection laws if he didn't allow deleting posts.

He could maybe allow authors names be removed from a post (ie. anonymizing) to meet the terms of the law, but even that is a gray area.

@OliverMattos My understanding is that the law isn't that granular, your posts are deleted if you delete your account and that may be enough

Why would he remove the ability to delete posts when he added the ability to edit them?

@PlasmaBallin Editing is only available for a short period of time, the ability doesn't last forever
