It isn't about freedom of speech. It is about actions having consequences.
He tweets in support of anti-Semitic ideas on Twitter.com (happy, @ionel?) and then he is surprised that advertisers do not want to be associated with that activity. Of course, he cannot say it is his own fault that he is killing twitter.com so he says it is the advertisers fault for pulling their ads from a company whose owner uses its product to support anti-Semitic ideas. Then he attempts to dress the whole thing up as freedom of speech or censorship. And some people are stupid enough to fall for that thinnest of argu,ents.
He clearly has freedom of speech and he clearly has no censors, not an internal censor nor a CEO that is empowered to stop him from doing stupid things that harms the business he owns,. As evidence of this I point to all of his many, many, many tweets. He calls people pedophiles, files lawsuits to stop people from publishing reports about his product, and any number of other self-inflicted wounds. But it is never his fault. It is some evil cabal out to get him.
And when he tells the very people he blames for ruining his company by refusing to buy his product they can F... themselves, how is anyone surprised that they do not spend money on his product? Why would they ever at this point? He is just too toxic a presence.
Then you get guys like @headshuck who think it is war. The stupidity of that take is hard to quantify, and I spend all day, every day quantifying things. These are customers, sorry, were customers, who he is, in theory, trying to win business from, not enemies attacking him.
