I have long felt that the computer industry course-corrected with mobile phones. They made a mistake in the early years of computers by letting users do things like install software from unauthorized sources, modify software to run to their liking, or even strip out the operating system and replace it with an alternative. Now we get things like TPM, Pluton, chains of trust, and DRM. 2% (rounding up) to protect users from malicious software tampering, 99% (rounding down) to extract rents from users and to track them for advertising or other purposes.
