Maybe don’t draw art that you want to own on there?
Do you refuse to throw a piece of paper away because the landfill then owns it? If for any reason the thing you’re trying to convey is private and you want to retain ownership, then obviously don’t use it, and it’s great for you to call that out so others are aware. But to vehemently dismiss some functionality because you don’t find the utility worth the cost is short sighted and childish.
This could be a great platform, but almost completely ruined by an unnecessarily pretentious font.
