I wonder if the “never will” part is legally binding. Most companies bend over backwards to avoid making future-looking guarantees like that.
Nah. Such permanent guarantees are not legally enforceable, if a company really cares about it they’ll structure themselves in such a way as to make it very hard to change by having veto voices in their ownership structure who are for such things and will not allow a change, by writing language that requires some high majority of agreement of these owners that’s hard to come by to change such conditions.
At best you get it in a contract when you use the software but guess what, that contract can and is overwritten as soon as you use a new version of the software with a new contract, feel free to use the old one full of one-click machine compromise vulnerabilities forever if you’d like but in reality you have no choice but to update and accept the new contract.
