See - I read that exact same message, and applying my "contract legalese" filter I come away with the utter opposite opinion. "we reserve the right to disable or remove any website project on Netlify’s Free Usage Tier without notice at our sole discretion" That's the promise. Full stop. Everything else is filler words to make that seem more palatable to people. You are being misled because you are not reading the contract as "a list of things netlify MUST do". Making assumptions based on anything else is folly - you are trusting a commercial entity to be "nice" and that's a really, really bad thing to trust them to do.
