Of course it is. As always a choice between visual quality and framerate.

DF did a pretty decent video on the whole 30fps question. https://www.youtube.com/watch?v=i9ikne_9iEI

Yeah. Though the third party users are probably are the heaviest users so probably have an outsized impact on the content of various subreddits. So no, I don’t think the lack of 3rd party clients and those users will kill Reddit, anymore than its killed twitter or Tumblr shennanigans has killed tumblr. That said I did just join today, and I do actually wonder given the death of 3rd party clients and the IPO when reddit will try to squash NSFW subreddits and posts. Thats the kind of thing I’d expect as they IPO and chase advertisers.
