I had part of my comment responding to this point, but I wasn’t sure how to best phrase it so I cut it off.

I don’t believe for this to happen enough at any frequency to be a valid reason. People usually knows their pain point, and go to great length trying to address that (normally spending a lot of time due to, well, spam-ish marketing). And to be frank, most products are not game-changing things that magically solve a problem no thing previously could have solved. People are already using tools and solutions for their problems, and if they are looking for a better thing, they already know which tweak it needs. They just can’t differentiate the solutions between a sea of junk marketing.
