My bank grandfathered me onto an account TOS for a decade before giving me a "move to our modern accounts or close" ultimatum, my electricity provider has legal limits to what the the unit rate and landlords are limited to one rate increase every 12 months, which in my city also has its amount limited. If my phone, internet or TV company wants to increase prices that voids any contractual lock in period I may have been held to otherwise. I work for a B2B company and we do gate features depending on which revision of the TOS the client has agreed to. In short, other countries outside the US _do_ hold other service providers to similar standards.
