The US Federal Trade Commission (FTC) noted the illegality of the use of stickers on products that claim that their removal will invalidate the warranty. A number of companies have notified this and also that the use of non-branded parts and tools for repairs is also not prohibited by law and cannot cause a loss of warranty. The warranty on the use of parts or components licensed by the manufacturer only also caused FTC dissatisfaction. The names of the companies that received letters from the trade commission are not disclosed. It is known that companies from the automotive, gaming and mobile sectors were targeted. Since there are not so many gaming companies, most likely the FTC warned of violations of either Microsoft or Sony. Apple already got the catch from the Federal Trade Commission, and then abandoned the practice of withdrawing the warranty for third-party iPhone 7 / 7Plus screen repair. True, the story repeats itself again, but already with the iPhone 8 / 8Plus.
