Gonna make a lot of assumptions here, but they probably apply to most people.
Whilst I do dislike celebrity culture and the idolisation of celebrities in any era, I don't really see anything wrong with "YouTube fame" in the wider context of fame and celebrity. People have always become famous for stuff that seems trivial and boring to older generations. YouTube fame is just an extension of celebrity culture, and YouTubers do provide entertainment to millions of people so having any issue with it is ridiculous. Yeah, some YouTubers do stupid stuff and act like idiots, but you won't find anywhere in music, entertainment, film, etc. which doesn't have it's fair share of people doing fecked up stuff. Most YouTubers are good people, making videos to entertain their fans and aren't harming anyone at all.
Assumptions and stereotypes here, plus not fully serious, but I would categorise people who hate YouTubers, YouTube fame, social media fame, etc. into two categories. Category 1 would be people who grew up in the 70s/80s who have strong nostalgia for the era and haven't quite moved on from it. People who like rock music, metal and think anything relatively modern like internet celebrities and rap music are garbage. Fail to realise that people got famous for stupid stuff between 1970-89, and celebrities were far worse people back then than they are now. Questions the lifestyle of rappers and thinks "rap music" isn't real music, without realising that they sound exactly like the older generations in the 70s who hated Rockstars and rock and roll.
Category 2 is people who grew up in the late 90s and 00s, the "I was born in the wrong generation" people, who think modern is trash and romanticises an era where the best parts are highlighted and the bad music, famous idiots and all the other bad stuff during that era have been forgotten. Hates YouTubers because they're "untalented" and rappers because they're "morally bankrupt" but won't look into what "Rockstars" did in their spare time.
That being said, the notion of "the modern celebrity" is just an illusion, people have and will always become famous for stuff that might seem mundane to a lot of people, that's how celebrity culture works. People will always find morally corrupt "celebrities" to idolise. Though, I would rather my child look up to an asshole like Jake Paul or KSI than to look up to someone like Jimmy Page.
