The reach of these kinds of lawsuits (see also the Yahoo one from a few years ago) goes far beyond the affected employees. For example, I'm a dev but I've never worked in ops or any other role where I was considered "on call", so I have never had the opportunity for being in the plaintiff class of any of these kinds of suits. But just reading about them makes me reconsider a lot of things. Despite not being "on call", I have still put in tons of unpaid overtime over the years, which is unfortunately considered typical for a software dev these days. Reading about lawsuits like this has essentially motivated me to stop doing that. If others are getting paid for overtime (even if it's through lawsuits) but I'm not, then I won't put in those extra hours. It's changed my life for the better, despite not being directly affected.
Restaurants already keep notes on their customers and refer to them whenever you call or make a reservation online. If you're a less-than-ideal customer, they won't do something as overt as refuse service (unless you did something truly horrible last time you were in), but they might be more likely to squeeze you in for a last-minute seating during a busy time if you've got some good things about you in the notes.
Maybe some restaurants. Not the one I worked at. And unless they share them in some kind of city-wide (or international) database, it's not the same effect as uber refusing to have you as a customer any more.
The only reason it works for Wikipedia is because everything must be externally-verifiable ("citation needed" and all that). On Wikipedia, trust in the crowd is not only unnecessary, it is actively discouraged. That doesn't work for all situations, and as we can see from this story, bad things can much more easily happen in cases where external verification is not available.
It's very strange that when you click or touch down on a button, the shadow spreads out more, as though the button got further away from the underlying surface. It seems like any "press down" sort of action should, well, make it appear to move down, not up.
