The problem with ads for me (other than the bloat and the privacy invasion) is that the tracking is just shit.
Whenever I'm signed in on Youtube I get non-stop ads for Squarespace (due to being a web dev I imagine). No matter how many times I mark the ads as irrelevant, they keep showing them. I've seen Squarespace ads hundreds of times, wasting my time, and Squarespace's ad spend.
When I open Youtube in a private browser and go to a gaming channel, I get ads for games. The ads are actually interesting, and I discovered three games this week that I hadn't heard of.
I would rather Youtube showed gaming ads on gaming channels, instead of all this tracking nonsense.
I've tried a lot of the newer city builders and the 3D just does not do it for me. I find it clunky and awkward.
