I would also like to point out that the developer's Patreon has been mysteriously cited as "in violation of community guidelines." Apparently, making a libre client program to the world's most prominent video sharing platform is against Patreon's "community guidelines." They should just be transparent and say they suspended it for preventing the flow of money into Google's wallet.
For proof, here is the developer's Patreon page as of 12 October, 2019. Linking through the Wayback Machine to avoid Cloudflare: https://web.archive.org/web/20191012222327/https://www.patreon.com/omarroth
