Not to sound conspiratorial, but isn't Gab.ai trying to market itself as a censorship-free twitter clone for alt-right types? If so, what better way to generate brand awareness and users than by picking fights with liberals?
Unfortunately (as one might be able to tell from the election results) not everyone hates Trump. In fact his supporters would likely make a sizeable consumer base.
Seems like it, I Googled him to get a better understanding and several prominent links were Breitbart articles about other posts of his that were removed from Twitter and Facebook. Looks like a lot of it is just drumming up support for his completely free speech Twitter clone.
That'd be the US government's version of acceptable free speech. You can't just start a legit business with VC backing that allows terrorism and child pornography. And it gets more and more expensive to run the service the closer to the line you allow.
