In the US, not that I'm aware of. I suppose it would be possible to add a "poison pill" ("If we change this, we'll pay everyone $X dollars") to then just make it a normal contract, but again essentially no company would be willing to do that because it extremely limits their options. Also, "forever" is a lot shorter than people think, it's only as long as the powers-that-be are in a position to enforce a contractual position.

nonsense. there's millions of ways.

one is to be upfront about it on every advertisement and service description... can't get any easier than this. and is as effective as the complicated canary shenanigans.

Did you even bother reading the thread? What happens when your company gets sold, and all the old promises are thrown out the window? This has happened many times before (just ask Palmer Lucky about Facebook logins for Oculus), and that is what people are asking is preventable, and your suggestion does nothing to solve that problem.

the marketing will have to remove all promises, so customers can move out.

they get around this using platitudes, like "do no evil".
