On mobile YouTube, where I see most of my ads, it's also almost impossible to click the extra-tiny shishkabob menu next to the ad without first clicking the ad a bunch of times. Until ~6 months ago, this made the ad disappear, and made it impossible (or at least, I didn't see how) to request they not show you the ad. And now it looks like you engaged with it. I don't think this accidental clicks was necessarily their intention, but they certainly decided to make that shishkabob smaller than all the others, which was absolutely a deliberate dark pattern. Presumably to increase the effort required to/decrease the frequency of users taking this action.
Now they've taken to pitching me pretty extreme propaganda from the likes of The Epoch Times.
Best and brightest, indeed.
