You have described everything clearly. You are absolutely right, for some users it is difficult to leave a community that supposedly supports them, even with little vote. And I say supposedly, because from my point of view it is only fattening the account to filter the largest amount of steem through the accounts involved. And give little vote to users. The user tends to look for where they are most supported. This is seen in several communities where the support of the Steemit team has died. However, those users are wandering around various communities, which I will do now, trying to establish myself in some communities.
