this could not be timed worse for Tumblr which is in huge hot water with its userbase already for its CEO breaking his sabbatical to ban a prominent trans user for allegedly threatening him (in a cartoonish manner), and then spending a week personally justifying it increasingly wildly across several platforms. the rumors had already been swirling that this would occur, but this just cements that they were correct
Pretty much, yes. The GDPR allows users to access, modify, and delete their own content. The TOS license all user content to Reddit. There might be a conflict if they try to sell previously licensed content that a user has blanked or requested to be removed, not sure how that one would work out, but any content still on Reddit is fair game.
I’m guessing Tumblr and WordPress have similar licensing clauses ok their TOS.
