These tools are useful, and on a Mac if you want Rewind, you have to know you want it, go out download it, pay for it, install it yourself .. and you knew what you were getting into the whole time.
Having a tool like this planted in your device without your consent is pushing your userbase over the edge.
If they made it a separate feature you had to manually install, like Windows Sandbox or WSL .. they could have avoided shooting themselves in the foot.
