I think Meta is doing a decent job with Instagram. I mean except for collecting all possible data and psychological profiling of users to serve them targeted ads, it’s a decent enough platform. And the only one still allowing for engagement with your actual friends rather than exclusively professional content creators.
I think allowed shipping destinations are defined product by product. At least in the opposite direction it’s true, when I look at the US Amazon, some products are available for shipping to EU, some are not.
