There’s so little demand for privacy in the U.S, that politicians have no reason to work toward it. It’ll stay that way until enough people refuse to engage with surveillance based services. I don’t honestly see that happening. Even people I know who claim to care about privacy routinely violate their own privacy and that of other people for mere convenience.
And this is why politicians refuse ANY privacy regulations in the U.S. If big tech and their advertisers couldn’t use every means possible to collect every scrap of info to identify and analysis you, just think how upset they’d be.
This is probably part of the enshittification process. With personalization on you would get pushed to the smaller companies that pay the store site to put their ad at the top of the page.
With personalization off the site doesn’t know what it thinks you want and how to give you what it is being paid to push at you instead of what you want.
