They already are. Most countries have consumer laws that limit terms and conditions. The same in many other areas (residential renting in many countries, exclusions for negligence that causes injuries or death,....).

Most countries have competition laws that also restrict what companies can do. That is the point here. We need need government intervention when the market lacks competition.

Maybe I misread the GP comment, but there is a big difference in governments defining guard rails for what isn't allowed in any T&Cs and governments being involved directly in every T&Cs.

[graemep]

Yes, but providing fair appeals does not require the government to be involved in evert T & C, just requiring things such as approvals be carried out impartially, and with some channel of appeal.

Something like an Ombudsman scheme for app stores would do it.

That seems reasonable enough. Down with governments and regulations and all that nonsense, but in reality I don't see a problem with governments setting reasonable guard rails for what any T&Cs can or must include.
