"Everyone hates YouTube" is an argument that has a lot to overcome. All objective indicators suggest it is incredibly popular, and growing in popularity, pretty much across the demographic board.
This is pretty common across social media as well, surveyed sentiment towards it often negative while usage is high. I suspect it's because of the addictive quality.
But sentiment toward YouTube isn't negative. It is the most reputable social media in Morning Consult's brand reputation survey. It enjoys a higher reputation score than things like Cheerios and Tylenol. I don't think you can separate the reputation of the platform from the collective impression left by the creators, and people like the creators on YouTube. And, I propose, people largely DGAF about the platform features and presentation.
I hate it, but I still use it. The platform sucks, but most of the content isn't available anywhere else. Between the infrastructure cost, the difficulty of monetization, and the immense user/create base already invested in the platform, I don't think it's possible for anyone to compete with YouTube without government intervention.
