Technically not legal, but depending on the wording, there's a ton of gray area in what's considered warranty-covered damage and what's not warranty-covered damage. Companies absolutely take advantage of the gray area, even lying in some instances because they know that their users would rarely have the know-how to call them out on it and demand rightful warranty coverage. LTT's argument is that if there is such large legal gray area on the warranty, it is meaningless to provide one to begin with
