I don't think anyone's talked about him on this forum before, but Jonathan Paula (jpizzle1122, later Jogwheel). He was one of the guys who created Is It a Good Idea To Microwave This, a YouTube show that ran from 2007-2011. Episodes regularly topped 100k views which was nothing to scoff at by the standards of pre-2010 YouTube. It was made by three guys: aforementioned Jonathan, Jory Caron, and later on Riley McIlwein. The show stayed pretty popular until they ended it of their own volition in 2011. They ended on episode 300 and just didn't want the show to get boring, which is fair enough. The latter two guys more or less fucked off and haven't maintained a consistent online presence since 2011.
Jon, however, maintained his channel afterwards, uploading other stuff like movie reviews, food challenges, tech reviews, let's plays, and other content from these sorts of generic online genres that have already been done to death. Though competently made, there just really isn't a whole lot of reason to watch these videos over the thousands of other Youtube movie reviewer type channels. The only ones that ever topped the Microwave show for views were the ones that used unabashed egregious clickbait. Even now these remain the most popular videos ever uploaded to his channel.
The microwave show was Jon's bread and butter for years and was the main thing his channel was known for, so logically when he stopped making it, his channel's view count started declining. Unfortunately, Jon apparently doesn't understand why this happened, and he even made an entire video in 2016 talking about it:

This video can basically be summed up as 8 minutes of John getting buttmad about people not watching his shit anymore, and then blaming the YouTube algorithm for not jamming his milquetoast movie reviews down the throats of people who clearly aren't interested. He also doesn't do a very good job of hiding his ego, doing things like claiming his content is "objectively better than it's ever been" and that the videos themselves aren't actually part of the problem. He makes this strange argument about channels declining over time and he seems to think he's owed viewership and popularity simply just for being on YouTube for a long while. (Despite also willingly discontinuing the thing that made you popular in the first place) He also does mention the clickbait videos but pretty much handwaves that entirely and just goes "yeah but who can blame me?" before moving on.
And obviously this post wouldn't be complete if I didn't mention his Twitter political sperging. It ebbs and flows depending on where we are in the US election cycle, but it's definitely a regular thing for him to be bitching on Twitter about whatever flavor of the week political thing. Even back in the day he'd sperg at people in his comments section but I can't remember any particular instances of this.
Really, it's just kind of a sad turn for a guy I used to quite like watching when the microwave show was relevant on YouTube. It was a unique, funny, and very well produced show of three bros hanging out and cracking jokes while microwaving random shit. Definitely stood out among the stuff being uploaded at the time. Again, there's no shame in discontinuing the show and wanting to move on, but getting pissy that people aren't sticking around to watch you review capeshit and computer keyboards is pretty pathetic. You made the decision to kill the golden goose, and that's something you're just going to have to deal with. Jon hasn't uploaded anything at all to his main channel in three years now so I guess even he realized that eventually.
