Seriously doubt this is an API issue. The error itself would make it seem like it’s a problem with your browser, but unless you have some overzealous privacy extensions installed that are hiding your user agent, it’s more likely to be a temporary problem on their side.
Ubuntu is pretty upfront about any telemetry and allows you to disable it easily. A lot of Android’s telemetry can’t be opted out of, unless you happen to have an unlocked bootloader and can install a privacy-focused custom ROM.
These are not the same, although I get the point you’re trying to make. Ubuntu has a user-friendly interface, with a goal of making Linux accessible to all. But for anybody who wants to, it’s fairly easy to dig into the internals and become a “power user.” It certainly makes no attempt to stop you from doing so. Android, on the other hand, on MOST instances, locks down everything, with little to no overrides, even from the user, many times “in the name of security.”
