Your premise has the false dilemma: "If we can't perfectly block fraudsters from by-passing security checks, then we might as well have no security checks."
Another simple test is we can compare the amount of malware running on closed ecosystems with open systems. Which system hosts more malware: linux/windows or iOS?
I want to clarify that I'm not saying there are no financial benefits for Google/Apple. I am saying there ARE financial benefits to users and businesses on these platforms.
There is no false dilemma. You're just arguing for the sake of arguing at this point.
"In the meantime, Google’s story that this move is motivated by security it obviously bullshit. First of all, the argument that preventing users from installing software of their choosing is the only way to safeguard their privacy and security is bullshit when Apple uses it, and it’s bullshit when Google trots it out:

But even if you stipulate that Google is doing this to keep you safe, the story falls apart. After all, Google isn’t certifying apps, they’re certifying developers. This implies that the company can somehow predict whether a developer will do something malicious in the future." - https://doctorow.medium.com/https-pluralistic-net-2025-09-01...
