Settings > Safari > Motion & Orientation Access to disable this for iOS. I think it's disabled by default.

  Correct. It is disabled on a brand new iOS 12.2 install.

    The option isn't present on iOS 12.1.4, the previous version.

    12.2 is the release that mitigated this attack. So 12.2 also contains random noise in the sensor data - releases before this did not disable it by default (according to the article).
