User friendly features are only incentivized in a competitive environment. Until Firefox or Edge catches up in both performance and implementation compatibility to make Chrome-first sites work, extension support isn't incentivized
Tbh I can’t even think of a place where competition solves user-friendliness—user friendly software is highly uncommon in commercial software, let alone more broadly (i’m eying you, canonical). There are a large number of user-hostile behaviors that stretch across industries: ad-funded software, app stores pushing microtransactions, wildly inconsistent interfaces and behaviors across DOM-driven software, opt-out beha…
Building software is hard, generally, and takes time, generally. Just because you can throw up a set of microservices in a day doesn't mean you can build a properly competing product that quickly. And as time goes on, the standard of competition gets higher and the barrier to entry gets higher, because user expectations grow over time. So most software isn't competitive.
