That's exactly the worry.
If Apple manages to pull wins here and in the OS bundling case it sets an annoying precedent. If the other corporations see that Apple's monopoly is actually enforceable in court, there's nothing in particular to stop them from following suit and taking away choice. Quite the opposite really, plenty of incentive. Obviously they'd have to do it slowly to avoid a massive/immediate loss in business, but a shift away from rights (or an acceleration in shift away from rights) is virtually guaranteed... it's not like Microsoft doesn't have a track record for trying to force their bloatware on the world, and it's not like the RIAA/MPAA don't have track records for trying to keep their media off of open source platforms, just as the two most obvious examples.
On top of that, shout Linux all you want, but what if Intel and AMD both end up in agreements with MS/Apple about what software is allowed to run on their hardware? That's essentially what Apple is doing with the iPhone right now.
Small scale and probably a bit paranoid yes, but to say that we shouldn't complain until no choice exists is ridiculous... put a frog in hot water it'll jump right out, but put it in cool water and slowly turn up the heat and it'll sit there till it dies.
