This comment got a little off track but my main point is that restaurants will adopt it when it becomes "free money", which a sufficiently capitalized start up will be able to do for a period of time. They'll handle everything for you, and it will start helpful. But as investment money dries they'll implement more and more shady practices to make up that difference.
You're spot on though. This is exactly how it goes. I've seen many, many examples of this up close and as soon as a restaurant wants you to download 'their App' to view the menu you just heard the first click of the ratchet.
What strikes me as interesting about this whole discussion is that the tech world should be a lot more knowledgeable about these patterns and far less naive about the typical tech cycle. In a nutshell you can condense it to disrupt, gain marketshare, squeeze the lemon.
Whether it's Uber, AirBNB, Food delivery, Social media, Gaming or restaurants doesn't really matter. What I've seen - under NDA - would make your skin crawl and that's just the very limited sample of all companies out there, and it's mostly just Europe. But over the course of 200+ such in depth looks at how the tech world works it is very clear to me that the new middle-men are at least as bad as the old ones were.
I’ve seen about the same, except from the US side (even from companies that market themselves as “privacy friendly”).
I was just pointing out that this dystopia already can exist without tech. Tech makes it easier and takes power away from the little-guy (the server ‘doesn’t have to’ give the rich prick his expensive menu) but software doesn’t care about impressions.
