This is sad to see. I do see changes in the future though. Sites like Steemit are catching on (although I personally don't like the platform) and I believe that we'll see many more coming to life in the future. Of course, getting the amount of users like Medium, Facebook, Twitter & Google (the last 3 for advertising) will take some time, but I also feel that we'll see rapid growth in some of these platforms from the crypto users and supports, which in turn will bring it to the masses.
Sorry that your account was banned, that is bullsh*t.
I think it was banned for good reasons. As what has @Patatas has said, maybe it has something to do with bounties. Specially that there are non-English posters there who are really putting up that no one really understands because of broken English or even worst to scam people out of their hard earn money. It has nothing to do with the free speech or something. Sometimes you need to know where you stand, and at this point, looks like Medium is really fed up and says that they need to put a stop on it otherwise it will ruined the online publishing platform or social journalism that they established.
