How is it a strawman? It's not even a hypothetical, has everyone forgotten already the constant dramas from the era in which Steve Jobs insisted iPhone apps would be banned if they weren't of "very good quality" or whatever the BS wording was? And when he went on his personal moral quest against porn?
This seems like overreach to me. It's annoying but it's not like the Zoom app was silently letting people watch me for hours through my webcam without anyone noticing - the app opens a full screen video sharing GUI for goodness sake. Is being joined to a VC without me wanting it when I click a link annoying? Sure. It also serves the attacker no real purpose and thus has never actually happened in the wild. It's also easily fixed. This is a storm in a teacup.
Moreover it seems from the last discussion of this on HN that videocall firms do this for a good reason - lots of users get confused by bad Safari permissions GUIs and end up locking themselves out of the app by cancelling the URL open prompt without thinking (which is apparently persistent!) Then they can't join the call. So the only reason these firms are using such a bad workaround to begin with is because Apple screwed up their user interfaces: why is this not on Apple to fix?
This appears to send a message to Mac devs that a single troublemaking blogger can cause Apple to kneejerkingly nuke features in your app overnight, regardless of whether you are fixing them, whether they're serious or not or whether it will result in legions of confused and stuck Mac users. Not a great message.
