The issue is that those marketing and advertising are only partly about correct match making, they're also about deceit and the underlying goal is to drive revenue and ultimately profit in. Correctly matchmaking a need with your solution is just a side effect, ultimately they want to maximize how much they can extract from the population. Sometimes that's in providing a solid recurring solution, sometimes that deceiving someone to grab a few short term purchases, sometimes it's convincing someone they need something they don't and an array of other unscrupulous strategies.
The issue is that in a competitive market, lying and deceit is often a relatively low cost effective strategy. You ultimately end with someone in the market who will stretch the truth to make their solution appear better than it is. Competitive forces make better solutions lower the bar and follow suit to some degree, either inflating their solution or debunking dubious claims from others (not too common due to liable cases).
So we get the race to the bottom of advertising which is why now I can't believe anything that isn't highly regulated and even then have to pick through each word for ambiguities that may be hiding some truth. I'm perfectly fine if you provide me a nice list of solutions I need that make my life easier at a reasonable cost. I'm not so fine when your goal is to pretend to do this while just looking for ways to extract wealth from me.
