Historically, voat and gab were set up because its users disapproved of the moderation on reddit and twitter. That differentiates the cultures on voat and gab from their predecessors.
That is an extraordinarily charitable way to describe the genesis of Gab, which actually has roots in a YC batch (that its founder, Andrew Torba, was kicked out of).
Could you say more about the Gab-YC connection?
Torba had an unrelated YC startup during the batch that was running during the 2016 election season. He was ejected from YC for harassing batch-mates; there's an HN thread about it you can find in the search bar. He started Gab at just about the same time as he was kicked out of YC.

Of course it exists everywhere in some measure (one can’t change the nature of humanity all that easily with just a website), but at least YouTube/Twitch/Facebook actually have some degree of value/utility. Voat et al appear to exist as little more than platforms for hateful bile that isn’t tolerated elsewhere.
Those sites weren't built with the specific intention of hosting people that were too much for other sites.
