It's just ads. If we're talking about some ad for a coffee maker, whatever.
Now their whole selling data to unscrupulous folks, taking money from parents via their kids, selling fake news that makes people hate other people (now that gets into the ad space...) ....
That's where I'd want to nope out.
And yes, I know, some sites and ads do terrible things. The actively hurt viewership. BUT, isn't that the same with everything? Even my groceries are getting worse as companies seek ways to increase profits without pissing me off; they swap out quality ingredients with cheaper ingredients. They change the shape of the bottle to reduce volume and hope I don't notice that the price effectively went up. Etc.
My point is not in defense of these practices. Rather, I'm defending "no shit" in all of this; welcome to the real world. Everyone is going to try and take and make as much as they can before it starts to actively show a negative impact.
So who is to really blame? Us, of course. Consumers of these practices are largely okay with it as is.
So yea, I don't have a problem with ads. They sort themselves out because people will stop using the products. I do have a problem with selling out data though, as people are largely unaware of the consequences and severity of what is actually happening. Ads however though? Who cares.
edit: Sidenote, I imagine an argument could be made that all and any ads are terrible. I definitely could agree with that, but getting rid of all advertisements across all mediums online or offline seems a tall order, and out of scope for this discussion heh.
