Good riddance? People will keep finding & buying things they need. If nobody’s buying anything from these businesses without invasive advertising & tracking then maybe whatever goods they were selling aren’t actually necessary? Of course there is nuance and edge cases to this, but in general I wouldn’t be surprised if society and the planet was better off once we stop producing useless garbage.
I don't think you've ever started a company with a new product. What if you make the world's best cheese grater. Nobody knows about it. You don't have connections to supermarkets. Smaller stores don't want to carry your niche item. You have $5000 budget to get your cheese grater out. How do you let people know about it? Online targetted advertising is basically the current established way to find those people who act…
All of this is to say that targeted advertising for niche, high-quality brands is only viable (at least if you're targeting someone like me) in an environment where search isn't beshitted by SEO, Google doesn't run a trademark protection racket, and reviews aren't 90% noise. Unfortunately, that's not the world we find ourselves in. At this point I'm more likely to just go to the kitchen store and physically examine cheese graters to find one I like than relying on the internet.
