Gab swapped one set of vendors for another. Now they are at the mercy of Cloudflare, ProtonMail, Wordpress, their new underlying server vendor and any security vulnerabilities that pop up in their haphazardly maintained forks of the libre software that powers their website.
This is not a high effort endeavor, the reskinning Gab did was the bare minimum to steer users to buy Gab Pro and try to stop said users from getting scammed by competitors (press F12 on a Gab page on the main site to see their hilarious warning message).
