I've heard it makes it illegal for vendors to void a warranty merely because you used it in an 'unauthorized' fashion. i.e. it puts the burden of proof on them to show that your modifications actually damaged the product. This protects peoples' right to repair by ensuring that they don't (effectively) get retaliated against through warranty invalidation when they get their products repaired by 'unauthorized' parties. I think the relevant clause might be 15 U.S.C. § 2304 (c) but I'm not sure: https://www.law.cornell.edu/uscode/text/15/2304 https://www.law.cornell.edu/uscode/text/15/2304 The enforcement of this act has been quite awful in the past, so I guess they're now planning to do a better job of it.
