Wait a minute, don't you know how Steem works? It is a proof of brain system with free 2.5 free downvotes per day for every account. Free downvotes are required for abuse fighting and over rewarded low effort posts. It's just a system calibrating itself for more equal playing ground for all participants.
It's just a passing thing. You're not been censored, everyone can still see your post here and on Youtube. It is better to get used to downvotes instead of going berserk before truly understanding how daily Steem reward pool works, everyone has been downvoted here before, join the club.
Also if you ever want to leave, someone else will take your place. Blockchain has no feelings.
