I don't see it working in Sweden either.
- We have apps for identifying ourselves digitally, most popular being BankID, but there are alternatives like Freja E-ID and various others.
- We have apps for easy money transfers, Swish being the most prominent, and it can be used to pay in stores and such as well.
- We have apps that combine economy management and shopping, I've no idea how popular they are, but Klarna comes to mind.
Amazon launched here a couple of years ago, and I think they've clawed out a niche in the market shockingly, but they're not the "go to marketplace" for everything. If I want to buy electronics there's like at least half a dozen online (that often have physical locations) stores I'd go to first. Same thing for larger appliances, clothes, make-up/beauty/skin-hair-care, shoes, sporting goods, furniture. Amazon is mostly for like weird niche stuff, like it's the only place I could find a detergent that's designed for robot mops that doesn't contain tea-tree oil. Amazon is also a decent place to find mass-produced cheap garbage tat, like LED string lights and what have you.
They also make use of the same delivery services that all other stores do, so there's no point in using them if you want speedy deliveries. I also don't feel safe as a buyer when using Amazon because while I'm sure they have to be compliant with Swedish consumer laws, I'm also positive they'll make the experience as tricky to navigate as possible. If I buy a motherboard from say Inet, and it breaks, I can just send an email to Jonas at Inet and they'll sort it out. Nothing will be that straight-forward with Amazon.
Anyway, the point of that massive segue is; if a MASSIVE specialised company like Amazon has failed to fully establish themselves in their own niche here in Sweden, how on earth would a broken microblogging platform manage to "out-compete" other, trusted, and established services?
Musk is aiming to use twitter for a niche that doesn't exist. Literally the only demand for this dream platform of his, is himself.
