My favourite channels on Youtube, once they become large enough they start to include sponsoring/ads. Production quality goes up, but my enjoyment and trust goes down. I prefer the old hobbyist internet over this manipulative and shallow ad-driven one. So I install adblockers on every system and I don't understand people that look at ads to support content creators. If you want to support, then why don't you use Patreon or subscriptions? (I wish micropayments had worked out)
A lot of shady advertising brokers also push malware. And many sites are only able to be used with some type of ad blocker because of how intrusive the ads are. Also the bandwidth savings can be huge in bandwidth constrained environments.
