The surveillance harms/thread of a Chinese state owned app need to be fully explained to really make sense.
Unfortunately, going into the minutiae of app based surveillance technology would run head-on into other surveillance based tech from Facebook, Google, and so on.
And it would bring up the touchy subject of data privacy. Oh gosh, if Americans had data privacy this would impact a lot of American businesses based on surveillance tech.
So let's just accept, on good faith, that what the Democrat's portrayed as Trump's Xenophobia, was OK as a natsec issue when Biden did it (no xeno here, folks!), and now that Trump has his bargaining position it's time for "let's make a deal!" (and that Republican who stalled the initial TikTok ban has probably been a good boy this Christmas, and maybe deserves a quid pro quo gift).
I suspect it might have something to do with the prevalence of earthquakes, the likelihood of said structures being damaged in earthquakes, and building codes (I've heard) that require re-building on a regular basis.
When you build you civilization on active volcanoes having long-lasting buildings may not be a reasonable assumption.
And, yes!, they have insurance. So if you can insure buildings in volcano country, you can insure anything, anywhere, maybe?
No matter what happens with Devin specifically, I think this is a really important topic and I enjoy reading updates on this kind of review every time.
