That's exactly what Tumblr's ex-users don't want, however.
Those Tumblr users want a place to freely exchange what they like, whether that's cute cats or hardcore porn.
That's what made Tumblr so beautiful. I'm sad to see it (apparently permanently) go.
Then again something nice is coming out of it as well: The main competitor is now the non commercial, federated, ActivityPub based Fediverse, frequently referred to as Mastodon.
