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.
I think the point is that it’s difficult to attribute that to communism in any meaningful way where you’re comparing it to non-communism. Like if those 100 million people would have died anyway, how to do you say ‘it was communism that did it’ since maybe more would have died under the next most likely form of government that would have been in it’s place. How many people have died for Democracy, assuming that both world wars and countless other ones were fought to defend it.
