Seriously, _what_ are they gaining by eliminating access to third-party clients? If they want usage data, they already have all the API calls. If they want more ads, they can change the APIs to inject them.
Their ads platform is damned near useless compared to their competitors. It's a wonder they have any revenue at all.
Their moderation is wildly broken, frequently leading to blanket account bans of anyone participating in a thread close to content deemed inappropriate.
