Yesterday when I read the announcement, I though DTube was leaving. Glad to learn that it's actually DLive, which I never used due to its lack of decentralized video hosting.

One fishy aspect of the farewell post is that it doesn't provide actual technical reasons for leaving Steem. The "Why is DLive migrating?" section is super wish-washy and mostly discusses the imperfect nature of influence proportional to power. But this shouldn't actually concern a service provider. For example, as long as people post to DTube and they keep getting a slice via beneficiary rewards, then all is good. As such, it was clear to me the DLive explanation was a red herring... excuses.
