I never understood why they even had that clause in their contract. You’re already not allowed to change the terms of a contract after the contract has been agreed (because otherwise what’s the point), you don’t need to independently include wording to say you won’t do it. Equally removing the wording doesn’t allow you to make those changes.
So effectively they had some wording that didn’t give anybody any additional protections, then removed it, thus not removing any protections. They then acted as if that weirdly allowed them to break the law, and then broke the law. Then when someone pointed out that’s not how it works, they backtracked.
