> It’s sadly not uncommon for businesses to promise various services and then unilaterally change their minds. While I’m sure that there are some exceptions, most TOS have a ton of “we reserve the right to change our minds whenever for whatever reason, without warning”

I was under the impression that one party cannot unilaterally modify the terms of a contract without offering consideration to the other party, and the consideration can't be "we will continue to perform according to the terms of the contract".
