While some may argue in favor of the witnesses fighting for the community, several exchanges already put Steem and SBD wallet in maintenance.

Are you so ignorant of what is going on as to think that was any kind of a voluntary action on part of them? The STEEM and SBD wallets are "in maintenance" because the fuckers have powered up their customer funds to participate in governance on Steem. That is potentially illegal and may open these exchanges to very expensive lawsuits.

One other exchange has announced it is looking into adding STEEM because it wants to support the community.

The Tron team pretty much decided they are going to fork their vision of Steemit unto the Tron blockchain and at the end of the day, people are going to go where the money finds home. Most of folks who know what's been happening in cryptocurrency knows where the money is going.

Centralized mainstream platforms are where the real money is.

The only selling point Steem has is the fact that it is free from censorship. That is the ONLY thing about Steem or any other blockchain-based platform heavy hitters among online content creators are potentially interested in because not even they have actual freedom of speech on centralized mainstream platforms. Even when the price of STEEM was $4-8$ in the spring of 2018, Steem did not attract any mainstream content creators from YouTube or anywhere. They couldn't be less interested in the kind of peanuts the space is capable of offering at this stage of adoption. What gets their attention, however, is the lack of centralization and thus freedom of speech. Ask Hive account@jarvie, if you don't believe me. His brother has a large following YouTube.

A centralized blockchain where some single Chinese entity is dictator will not interest anyone of any value.
