People keep saying this as a meme, but they guy is just... alive. He's alive and making content (recording himself lazily playing games) where he gets a bunch of donations from trolls (because he's a laughing stock, and the market for this will never die) and hardcore followers (fans from decades ago).
This is not being unkillable, or teflon, or whatever. He has to do this as a job because his financial demands are high (wasted on gacha gaming) and because any other job he'd have would be entry level, far more exhausting, far less rewarding.
So it's obvious why he needs to keep going. He is not cancelled because he doesn't go out of his way to do things that could cancel him for good (which would have to be him going on a blatant racist tirade, or sexually assault someone)...
So again, he's just alive (and aging poorly).
