Entirely intentional because they want to filter out anyone who can see how scammy it looks, so they don't waste their time. This is bulk spam stuff. If they are actually targeting you, it will look very real.
I don't buy it. The actor running the website likely gets paid for every user that installs the app or possibly even every user they direct at the app.
Even in the unlikely case that they get paid for achieving some later payoff, the "work" on the way there is almost certainly 100% automated so there is no harm in spraying the attack more widely (as opposed to Nigeria scams where pre-AI, pre-slave-farm, the scammers would have to invest significant amounts of a very limited resource - their time - on each victim).
