"So witnesses are doing that softfork 222 in order to protect their positions in the top 20."

for one, I am pretty sure no one did this to protect their position. As I outlined in my post, this was done having Steem at heart. All for Steem. Steemit Inc's stake as far as we can tell is not voting for witnesses, so that would not change. It is preventing the Steemit Inc stake specifically, which is bound to social contracts, to vote. As they where not voting anyhow obviously this doesn't change anything.

• Or are you suggesting that Top20 (or better said all participating witnesses including even more beyond top20) were afraid of being removed (by using that big Steemit inc stake) because not in line with the "Tron Vision"?
