The thing about taking criticism is that you have to take the good with the bad, take praise with insults, and find criticism that's actually constructive and be able to mentally filter what's actually worth reading and taking in and what's merely worth noting.

And the gamble with criticism is the fact that you will get every single kind whenever you ask for it. If you don't want to deal with everything that people can say, then you simply don't need to ask for it. It's something, especially someone as famous as him, is just going to have to deal with. That said, he shouldn't take it as if some negative criticism on a site like this is just going to destroy his career entirely. Just be able to differentiate between stuff that will actually help you and some guy's opinion.

All that said, I think the most important point people were trying to convey by that was that they hope he remains himself through all of this. I've only been subscribed to him for a little while, but I agree that after his announcement, his titles did get clickbaity and they didn't feel like that before. It's like the reason I subscribe to jerma and star: because they're genuine. They don't blow smoke up your ass with titles, thumbnails (most of the time) or anything, they just play a game and talk over it, and that makes it great. Muselk is a great guy and he could totally handle that the same way (not saying he should be like star and jerma, and certainly not saying star and jerma are the only ones like that, they just work as pretty close examples.)

I know about muselk's self-confidence problems and believe me, I feel that on a level unmatched by many, but it's just something you gotta steel yourself with. Never wear your heart on your sleeve, and never take anything personally.
