Afaik it’s not “Android things”. Apple devices also use location to use some BT functions if I correctly recall.

That’s actually an accessibility feature intended to keep the eye level roughly at the same position; the person saying “I hate it when editors do it” is really not understanding why this is a feature and not a bug.

Luckily browsers can mute tabs now!

And don’t forget under construction gifs.

Google Assistant doesn’t meet the OP’s requirements: it’s not open source.
