alt Hacker NewsNo, at least not in all cases. Customers incur review costs and potentially new risks if you change contract terms unexpectedly. In my business many large customers will only adopt our ToS if we commit to it as a contract that does not change except by mutual agreement. This is pretty standard behavior.
I can’t think of any case where someone who cares about the contract (aka actual terms) would be okay with it just changing. Arguably, it violates the concept of a contract which in most legal systems requires a meeting of the minds.
Do you have any examples where it would be okay?
