I get the feeling that this is a skunkworks project for Meta. The fact that it's completely blocked in the European Union suggests that either they're doing something really bad (worse than Facebook), or they don't have the resources allocated to this project for their lawyers to greenlight it. And it just being a product built on top of the Instagram database would also fit in with that idea.
it seem like the Irish Authority isn't happy at all with the way the data is "commingled" with Instagram.
Could the fact that deleting the Threads account will also remove the Instagram one be connected to having this Threads thingy appear as a part/feature of Instagram instead of a self-standing platform?
It just bolsters the fact that I'm not install threads, ever.
