And the reason they could get away with that and stay in business is that (1) government has limited competition and (2) government has limited the ability of customers to sue those companies.
For #1, let's take an actual example. How exactly did the gov't allow MS to become an OS near-monopoly for desktops?
Per #2, most of the customers I was paid to screw didn't even know it. You can't sue if you don't know you've been manipulated. Part of the art of manipulation is not letting the manipulated party know they've been had. (I'm not condoning it all. I just ended up in such situations.)
Further, much of it wasn't illegal, just sneaky. Most trickery is not illegal and shouldn't necessarily be illegal.
