I asked the exact same question just a few days ago. The same hate you experience in your fighting, the top Vloggers on Steemit experience as well. I narrowed it down to envy. People want to do what other more talented or hard working people do and because they can't do it themselves they take the strategy to diminish the others.

Thank you for your post and here is mine: https://steemit.com/hate/@godcomplex/why-are-so-many-of-the-top-youtubers-hated-on-why-is-there-so-much-hate-in-the-crypto-community-against-successful-vloggers
