@onealfa has done the same thing about two years ago(no longer supporting "dual posters". At that time he was the biggest whale in Leofinance(he probably still is) and he's stance inspired plenty to no longer dual post.

Personally, after Hive was created I have not touched Steem for a while, then I thought I could just milk the rewards pool for a while, but after a while, I simply had enough with Steem. Drained my wallet, logged out and that's it.
