ripley manufacturers recommend you get a warranty all the time. do you?
whenever you build sometime there's always a chance you gonna fry it. manufacturers recommend you get somebody "experienced" to do your built.
what you fail to understand is that manufacturers just want to cover their azzzes by saying you shouldnt do this or do that, but at the same time saying "...but if you do, btw, here's the software..."
it all falls under product liability. just like htc mentioning in their websites that they dont recommend rooting their phones and if you do it voids their warranty. however if you device to root it, this is how you do ti. and they post explicit instructions on how to do it.
