There are already class-actions looming. Removing useful features (that may have factored into purchase decisions) like this tends to attract lawsuits and regulatory scrutiny. They've already lost/settled a few cases over the force-upgrade snafu.
I suspect these gpedit toggles won't be gone from Pro for good; and even if they are, MS will lose a lot of face and cash in the lawsuits that are sure to come. (Courts don't always enforce arbitration clauses and choice-of-law provisions like the ones that feature in the EULA; they almost never enforce max-damages provisions such as the ones that are rather amusingly there.)
See: Sony PS3 "Other OS" class-action, which recently settled.
