Understandably a lot of talk about YouTubers who have changed for the worse, but there have been a few who IMO have changed for the better. Granted, a good number are more towards the burnt-out end of the spectrum, and considering retirement within a few years.
Jacksepticeye for example, used to put on a more energetic "youtubery" persona that appealed to the algorithm, and now he's a lot more down to earth and considerably more pleasant to watch. That's not to say the persona wasn't still him, or that he was entirely fake for all those years, but I find his new content much more enjoyable than his older stuff - even if there is less of it.
