Linux distributions (keyword: distributions) have often shipped in a default configuration which can result in damage from overheating. There's no need to accuse the OP of "messing with something he doesn't understand."
Vendors often perform QA on hardware to ensure that it operates properly in conjunction with an operating system. When hardware is designed such that it requires particular operating system behavior to prevent damage then it is absolutely reasonable to require that operating system be used to maintain the warranty. Closing the lid of a laptop is completely normal behavior -- and it's a fact that many linux distributions ship with a configuration that will not properly suspend the device, leading to potential damage.
This is not a matter of "user unfriendliness." This is primarily a matter of hardware vendors limiting their testing to the behavior of certain operating systems (and thus limiting their warranty -- you can't warranty what you haven't tested; what isn't well-specified). I wouldn't be surprised if Apple refused to warranty a device which had Windows installed on it.
There's no need to get religious here. It's merely an issue of vendor support, and hardware which relies on particular OS behavior to operate safely.
Just to be clear, the issue has more to do with the vendor-supplied OS vs consumer-installed OS. My biggest overheating-when-should-be-sleeping issues have almost always been Windows on a Dell. But I have had it happen on a Cr-48 and MacBook as well.
