Because the plausible deniability model of SimpleX private routing and asymmetric relays is superior that's why. SimpleX the organization is subpoenable and targetable yes, but self hosted smp onion servers are absolutely not. The code base is open source, with reproducible builds so nothing to fear on the software end. Your claim that SimpleX as a company somehow lessens the decentralized model does not hold under this scrutiny.

Simplex is also very user friendly for onboarding as it just requires users to click a link or scan a QR code. I agree it has failings and those are to do with how foreign a userless messenger is for managing contacts.

I defend it so because I use it exclusively for contact now and I have a way higher degree of comfort knowing metadata is practically nonexistent.

Are there ways Tox is superior? I'm not familiar with the project please inform me if you'd be so kind.
