That, historically speaking, is not enough. People will find a away to screw up advertising, whether intentionally or not, so long as there is revenue to earn. Perhaps things have gotten better but when I used to dig into that code for work some years ago it was near negligent incompetent.
If you are going to recommend regulation the only thing that works, as exemplified by every other profession, is credentials: licensing and certification. There would be less bad software in the world if there were less bad software developers employed writing software and everybody else held to a minimum ethical standard.
Right now, at least before COVID, there was no motivation to write good software. Many developers, at least web developers whether front or back end, only goal was employability which often meant tooling to a tech stack and trying not to write original software.
Edit: I anticipate this will be downvoted extensively, because regulating minimal developer competence is always heavily down voted. It’s curious though that people claim there is a problem they want fixed only until they realize the fix applies directly to them, at which point the problem is no longer worth the effort.
