So... I used to run a restaurant that did this. We were actually one of the first places in the country to do it, back in 2014 - actually beta-tested the system for Next/Alinea before they commercialized it.
We noticed not a goddamn whit of difference in traffic patterns before and after. These restaurants just have really low price elasticity, so from the perspective of a place like Next, you may as well take the money, and from everyone else's perspective, well, you can do it if you believe in it (we did) but it probably won't change your business.
Something these articles overlook is that price differentiation of this sort actually implies a whole lot of other, more fundamental operational changes. You need to sell tickets (we got enormous pushback on this, but believed it was the right thing to do). Once you sell tickets, you almost certainly need to go from tipping to service included.
It's much less that the industry is resistant to change, and much more that diners are resistant to change.
