In a sense, I'm just agreeing with a fellow comment in the vicinity of this thread that said GDPR is already the EU's shot at banning (targeted) ads---it's just implemented piss-poorly. Personally formulated, my sentiment is that GDPR as it stands today is a step in the right direction towards scaling back advertisement overreach but we have a long way to go still.
Ofc it's impossible to blanket ban targeted ads because at best you end up in a philosophical argument about what counts as "targeting", at worse you either (a) indiscriminately kill a whole industry with a lot of collateral casualties or (b) just make internet advertising even worse for all of us.
My position here is that ads can be fine if they
1. are even somewhat relevant to me.
2. didn't harvest user data to target me.
3. are not annoyingly placed.
4. are not malware vectors/do not hijack your experience with dark patterns when you do click them.
To be super clear on the kind of guy talking from his soapbox here: I only browse YT on a browser with ad blockers but I don't mind sponsor segments in the videos I watch. They're a small annoyance but IMO trying to skip them is already a bigger annoyance hence why I don't even bother at all. That said, I've never converted from eyeball to even customer from sponsor segments.
I'd call this the "pre-algorithmic" advertising approach. It's how your eyeballs crossed ads in the 90s and IMO if we can impose this approach/model in the internet, then we can strike a good balance of having corporations make money off the internet and keeping the internet healthy.
