A badly flashed ECU can trivially wreck your engine. It can make it wear out faster. It can increase emissions.
I have no objection with voiding warranty repairs if you reflash an ECU. The important thing is that you should still be able to do it, and still be able to fix the car yourself and get replacement parts.
