We do not systematically prevent overclocking. There are lots of cases where altering the trip points is helpful, and if you look in vendor bugzilla databases there are multiple moans from people whose laptops now run slow, or in many cases are simply unusable as a result of Len's change. Given you can achieve some of the same result by not loading the relevant ACPI code in the first place your argument makes no rational sense at all. Set a taint flag, print a loud message but don't stop users actually doing things they intend as root.

As root you can erase the bios, lock the hard disk with a random password, reflash your video card .... Sorry Andi, you simply do not know better than all end users.
