If you look at it this way, then the computer manufactures are to blame, and you should be refunded by them.
That's the same as buying a car from CarCompany(TM) with an A/C and a Android Car touchscreen interface/radio/..., and an automatic android updates disables your A/C and changes the engine paramters so you have 20hp less... wouln't you expect "them" to fix it? As a consumer, you shouldn't have to worry if it's googles fault or CarCompanies(TM) fault, you should be able to take it to the dealer and have them fix it or give you a refund, or atleat 'do something'?
I'm not sure i follow the reasoning nor the example you gave. You can change and/or update the OS, both being outside of the computer manufacturer's control and that is assuming there was even a computer manufacturer and wasn't a desktop PC you built yourself (are you going to blame yourself for allowing Windows to install updates that slow down the CPU?).
