Probably the only way things won't egregiously suck is if there is sufficient competition. Having rules & regulations from some government entity might help a little (I am not a fan of completely unfettered capitalism), but can of course also go terribly wrong.

Unfortunately certain things seem to happen that make the "sufficient" and "competition" parts of the phrase not come together. Like, only the big orgs can do it; or the incumbents have ways of locking out new competitors (e.g. by vacuuming up most of the investment money even though they aren't yet profitable); or all the consumers are complete idiot glutton for punishment dummies who keep on using the evil bad stuff even when it is known to be evil and bad; or all the consumers wouldn't be able to differentiate between good and bad ux if their life depended upon it; etc.
