I had this idea of an evil group of people getting together everyday and looking at this data and somehow using it to puppet my entire online-life.
Sure, this group of people exists at every decent sized online company, and sure they're trying to get you to spend more time and money on their site/app/whatever, and sure this tracking data helps them.
Sure, SOME of these websites are peddling fake news or selling scams or preying on the poor/unfortunate/uneducated/etc. But I think that's the exception, not the norm.
Most successful companies make a product people genuinely like. There are millions of people that would buy and enjoy this product if they knew about it. Most companies are just trying to use this tracking data to get their product in front of as many of those people as they can, and as few people that don't want their product. They're trying to fine-tune their messaging to make sure it appeals to the people that actually like their product. They're trying to use it to figure out how to BETTER make a product people actually want!
Again, if you're saying that increasing our efficiency in sales is a bad thing, you're saying that capitalism is bad. But I've just come to see this data as something that enables product evolution to occur much faster. I see this data as something that's helping the world, mostly, get more of what it wants.
Like everyone says, Capitalism is the worst economic system, except all the others we've tried.
Unfortunately, I've seen too many product decisions catering to the manipulative aspects of adtech. UX often suffers, not improves with ads. Online platforms all seem to follow the same game ad monetization plan these days which results in messes like Frankensteinish apps--see official Twitter app.
As for actual hands on manufactured products or services, I'd like to know how ads improved the UX.
I guess your summary is about right.
> we live in a capitalist world, and I don't see that changing any time soon.
We were living in a capitalist world two decades ago, and we didn't have a significant amount of tracking back then. If you are concerned about your competition using tracking, then just try to make a better product.
