There's 2 separate universes here.
Devs and tech companies care only for UX, convenience, and reduced friction to use any service. They would put their granny's home address and SSN in the headers if it made a page load 10ms faster. Their incentives are all short-sighted to hit the next goal to outcompete other devs/companies and ship their end of history killer app that will solve all problems - and that will still get bloated and enshittified within 18 months.
Then there's us, a subset of rational people educated about how much data gets transmitted, who are horrified by the general state of being online, and are hard to impress when it comes to more than just saying "privacy!" when promoting anything at all.
IMO, we have to DIY and cobble together so much of our own protection, we're closer to artists that live a strange life that few people understand, seems weird from the outside, but we love for the peace of mind. Which is not enough to be any appreciable segment of the market to move the needle on any product worth real money.
