While I found the talk more compelling, it's also worth mentioning Moxie's 2016 article, "Reflections: The ecosystem is moving", for several of the key points: https://signal.org/blog/the-ecosystem-is-moving/
Are you just going to ignore the fact that the official Twitter account for Gab actively promotes white supremacist talking points? It only takes about 30 seconds of scrolling through their feed to see this.
I scrolled for not only 30 seconds or so but at least a minute. Nowhere do I find Gab actively promoting white supremacy. As far as promoting "white supremacist talking points" this is a pretty substantially different actually supporting white supremacy, and support for that allegation is still pretty vague. The closes things I found are:
> “Hate speech” is free speech, as decided unanimously by the Supreme Court of the United States of America.
Sure, white supremacists may be more keen to protect hate speech but this statement is factually correct.
> Right-wing platforms provide refuge to digital outcasts — and Alex Jones
Again, hosting a speaker is not the same as promoting or endorsing what is said. By this logic, Berkeley endorsed Milo Y.
> At some point you have to ask yourself: just who is pushing for the censorship? Once you learn who, there is no going back. You can’t unsee what has been seen. You can’t unlearn what has been learned.
Arguably echoes allegations that Jewist people control the media, but this is vague at best.
Furthermore, the account states that it would not ban left-wing speakers that had written hateful message about whites:
> The @verge defends the anti-white hate of @sarahjeong then turns around and maligns Gab as “alt right” for defending free speech for everyone (including Sarah!)
I think official Gab twitter account is consistent Gab's claim to allow all legal speech, including hateful speech regardless of political leaning.
