So by now it has almost 10K downloads.
Seeing that they are doing a giveaway on X by just downloading their wallet, it is likely that most of those who download it are just to get free sats.
Is this the official wallet from Tether? I need proof for that. And if it is a non-custodial wallet, then it's not worth using it. I would be better off keeping my USDT in an Unstoppable Wallet instead and feel more secure. By the way, it has XAU₮, maybe that's another reason why people using this wallet as they want to keep digital gold in personal wallets and not on exchanges.
That's Tether's official wallet. If you go to their website, wallet.tether.io, you'll see that it's their wallet. And yes, the main purpose of this wallet is to be able to manage USD₮, USA₮, XAU₮, and Bitcoin, but with so many odd things about this wallet, I recommend avoiding this wallet.
Why would a company as big as tether need to do a giveaway to promote their wallet? Instead, they should have introduced their wallet, and everyone would have started using it, and it would have gained a lot of hype, but this didn't happen. It is due to the factors mentioned above that it is not the wallet with the best features, and people aren't comfortable using it.
