If you're saying e-commerce would simply be consistent and secure product catalogs with fewer promotional and tracking dark patterns, web scripting would rely on a and extensible and functional library for manipulating markup documents, and a stable OS kernel with few dark patterns and no cloud accounts, many of us would be sold in a heartbeat.

I don't think you're making the counterpoint you mean to be.

Don't be naïve - the industry wouldn't be any less laden with surveillance crapitalism; the presence of that isn't a product of the pace of development, it is a product of the nature of consumers to eagerly suffer limitless abuse so long as the product "just werks", looks/feels polished, and doesn't require any kind of learning or discomfort.

Freedom from everything you enumerated already exists for anyone who cares enough to pursue it - robust ad and script blockers, operating systems with no coercion or user hostility, simple and stable scripting languages. They're not as polished as the products of manipulative and extractive abusers like Microsoft, Google, Apple, Discord, et al., and accordingly, users shun them, for the reason I explained above.
