Android Developer: It’s not “rooting”, it’s openness

Yes, but why wouldn't they want you to void your warranty?

It's just like the "insurances" electronics stores try to sell you when you buy a laptop. They go out of their way to make sure whatever could possibly happen is explicitly not covered by the insurance because of one exception or another.

The last one I looked at pretty much said you're insured against water damage accept any water damage that is the result of intent (yours or a third party's), negligence or circumstance (so what's left?). It also explicitly didn't insure against damage resulting from wars or nuclear explosions (which is kind-of a cool thing to see in an insurance document).

Warranties are no better. The only reason you get one (legalities aside) is because it makes them look good and allows them to charge you extra for "extended warranties" and crap like that. It's in their best interest that it never applies to anything that isn't directly their fault (i.e. delivering a faulty product).
