I mean I don't blame restaurants for only accepting orders over the phone, given that the alternative is a money-grabbing monopolist trying to take away all of their customers.

Yelp is another matter full of fake reviews and spam - I can also see why restaurants don't want to have a "social media manager" doing that for them.

I mean, you're using smart vocabulary "due dilligence", "Yelp" - but how much of that is literally spammy articles that have nothing to do with the real quality of the food in the restaurant?
