This will have ZERO impact on Apple, just like the countless prior ridiculous lawsuits did.
The lawsuits will be costly, but nothing they can't handle. They have handed a very simple and devastating sales line to their competitors, though, and taken a sledgehammer to their premium reputation. That's going to hurt sales and profits over the long term, and many consumers who slip away to other platforms will never come back.
Car analogies are popular here, so I'll use an experience I had with BMW. I had a premium model (650i convertible) with the V8 engine but, frequently it would run rough so I took it in for repair. The dealership cleaned the fuel system, but this didn't help. Next time they replaced the battery (yeah, I have no idea either). The time after that they changed the fuel pump. Each time they told me they'd fixed it and each time they hadn't. I went back again and, finally, someone fessed up that the injector pack on
every single V8 engine they'd made in the last 2 years or so had a design flaw. BMW's decision had been to avoid issuing a recall - because of the terrible PR hit this would be - and just change out existing packs if and when an owner complained enough. Sound familiar?
Anyway, BMW changed out the injector pack and, two days later, the engine shut off completely while I was driving, killing the electrics, the power steering and the power brakes. I was lucky as to where and when this happened as it could have been fatal at another speed or location. I told BMW that they can keep the damn thing if they release me from my lease - which they refused to do unless I rolled into another BMW. Given what I now knew about the way the company played games with customers cars and lives, I was never getting another one of their cars.
I hired a lawyer and sued them under the Magnuson-Moss Warranty Act. Without even having to go to court, BMW "bought" the car back from me, paid me compensation for my time and trouble, and paid my lawyer. I took the compensation check they wrote me and went straight out and bought used Mercedes, which I discovered was way better than the BMW.
The moral of this story being that Apple will find to their detriment that, once people switch to another platform, they may find out that the grass is actually greener, and won't come back.
