Rooster Teeth has been circling the drain for years. A lot of the old talent that made the shows good is gone, and a lot of them are gone because it turned out that they were abusive or sex pests, or both. There's been plenty of stories about how the workforce outside of the core "on screen" talent was heavily overworked and underpaid, and how there was bullying of lgbt co-workers.
Rooster Teeth really was a microcosm of the entertainment industry as a whole. People went to work there because they were passionate, and that passion was exploited. The exploitation and abuse was swept under the rug and covered up by a fake veneer of fun. For every video where Gus, Burnie, Gavin, Barbara, and Blaine were having fun antics the production staff were working 80 hour weeks and barely making enough for rent. I've worked with some people who previously worked at Rooster Teeth, I know a lot of these stories are true.
I was a fan of the company in 2007, but by 2016 I was pretty ready to see the whole thing shut down. Between the rapidly declining quality and the rapidly increased production (if you were subscribed to Rooster Teeth and Let's Play, and the side channels for both of those main channels on youtube you were getting flooded by like 20+ videos a day most of which were completely no effort, to appease the youtube algorithm) trying to dig through their deluge of crap to find "the good part" was exhausting.
There are apparently 19 seasons of Red Vs Blue. Fucking 19. I stopped watching 9 seasons ago, and by that time the show had already jumped the shark. I have no idea who was still watching. Also, RWBY is fucking cringe.
