The other aspect is that virtual desktops aka 'workspaces' become more important, and you tend to compartmentalize your work into related chunks. Almost all tiling managers work with 10 virtual desktops, which often feels like not enough, bizarrely.
It was a couple of years ago, just after he had hooked up with a gf, and he was doing weird AMA videos while wearing a smoking jacket. The general gist of the rant was his political beliefs on racism, wokeism, and 'there are only two sexes', it wasn't a full on hate-speech-apoluza, and probably not enough of a red flag for him to continue gaining in popularity.
For me, it coming a little while after Cody going a bit too RWNJ after Kanyon left him, it was enough for me to nope-out of his channel, but I have a very slim tolerance of youtube celebs anyway, I find most of them unbearable.
edit: given the 'My Girlfriend owns a macbook, F my life' video that was posted a week or two after his rants, I'm going to say it must have been 2019.
