The whole thing is full of BS.

Voat first launched in 2014 as a smaller Reddit alternative dedicated to "free speech," including explicit hate speech, extreme right-wing content, racism, and other content limited or prohibited on other sites. It gained traction in 2015, when Reddit finally banned several explicitly racist subreddits from its platform in a bid to limit harassment, and some discontented Reddit users decided to migrate over.

This is a "technically true" statement. In the sense that reddit banned Fat People Hate (a sub with 150k+ active users) and a few racist subs that totaled around 2000 non active users. The majority of the users who found their way to voat were the FPH ones.

Once again history has been altered to suit the narrative.
