I think that's overstating the issue here. Facebook built their empire on browsers being super super permissive about tracking. Critically, this tracking was (a) something most users weren't aware was happening and (b) something that was very very possible to curtail, because it wasn't something Facebook controlled. People started noticing, and they didn't like it. Browser makers and platform makers moved to make these unhappy people happier. Facebook got caught out, because their whole business is built on this invasive tracking. I am 100% untroubled by the way this is playing out. It's not a general case problem. It's very specific to Facebook's dependence on an accidental aspect of the web that, when explained, most people are horrified by -- and that was fairly easy to rework.
