Gab hosts many, many, white supremacists. It has become a dumping ground for every social network's rejects...the people who've been booted from Twitter, reddit, etc (platforms that have been criticized for being slow to remove hate speech and incitement to violence, etc.) have congregated on Gab.
This isn't a free speech issue, it is an issue of whether Joyent wants to have responsibility for spreading that kind of thing. They don't, so they aren't. They gave Gab time to sort out alternatives, even though the kinds of things Gab hosts conflict with Joyent's terms of service. I think Joyent is well within their rights to tell'em to kick rocks and go spread their shit somewhere else.
