People just need to quit using the term "PC" to refer to desktop or laptop hardware that happens to be running Windows. Laptops running MacOS are "personal computers," as are desktops running Linux, or effing phones running Android, for that matter.
I think the issue is that there's clearly as need for a term for the category of "things that usually run Windows (but you can also probably put Linux on it, and like, even one of the BSDs if you're feeling adventurous)". PC isn't a great one from a linguistic perspective, but there's not an alternative I've heard that seems likely to catch on. There probably also should be a better term for "laptop/desktop", since as you mention "computer" itself is not really narrow enough if you're being pedantic, but at the end of the day, right now the only really differentiator we have is context. In the context here, it was honestly more clear clear what was meant by "PC" in the top-level comment than it was whether the person responding to it actually misunderstood or was trying to make a point.
One can understand scepticism, but Duo isn't going anywhere. If you need a FaceTime replacement, just use Duo and put all the rest of that mess out of your mind.

"In August 2020, it was reported that Google was planning to eventually replace Google Duo with Google Meet, but would continue to support Duo and "invest in building new features" in the long term"
How do you know this? I don't know anyone using it so I've honestly been assuming it's the next to go. I've been using Meet with all my groups as it feels like a corporate solution and thus maybe more stable.
You say this like Google doesn't have a history of product ADHD where they create new products and cancel them within months. On top of that, they create multiple products for the same functions which means that people get confused about what's appropriate for a situation and what's not. At one point, Google had 3 different video solutions all active at the same time and none of them worked with the others.
There is quite a lot of regional variation in the States. I imagine Germans would prefer New Yorkers to West Coast Americans.
Multiple times, while on a train coming into the city from Portland, OR's airport, I've observed Portlanders strike up a grinning, friendly conversation with a New Yorker, noting their accent and inquiring as to what brings them to Portland -- and invariably the New Yorker has a pained look on their face like "why the fuck are you talking to me?"
Many years ago I lived in a sort of dormitory in Tokyo. The Americans and Japanese residents understood each other's personal space preferences just fine, but it was amusing to note the look on some of the Japanese people's faces when the Italians greeted them with hugs and kisses.
The Japanese say something like "nice weather, eh?" (ii otenki desu ne? - to which one replies "sure is! - "so desu ne!") -- which is mostly just a semantically little-analyzed pragmatic sequence functioning as a casual greeting.
