I'll start: the whole social media thing of everybody having to be a "brand" and the mainstream usage of corporate language (branding, SEO, engagement, content).
Related: trying to turn every single interesting post into a media empire. I remember a little while ago a funny video of a cat failing to use a treadmill hit the top of Reddit, and then suddenly it had its own subreddit and daily posts and just like that the magic was completely squeezed out in the pursuit of riches from viral fame
God pretty much everything related to social media, influencers, etc is just garbage
Commodification of identity. As soon as something gets popular, capitalism tries to figure out how to extract the most money possible. See punk for example. It went from a subculture, to a "lifestyle", to a fashion choice in the 2000's. Then every second pop artist from Kelly Clarkson to Adam Lambert tried to include loud guitar riffs in their music.
