> you work on mobile apps you will notice that full attestation is too slow to put in the login path
Hm, Play Integrity isn't that slow on Android, from my experience.
> don't think a good security engineer would rely on atty as "front line" anti brute force control since bypasses are not that rare
I'm not privy to device-wide bypasses of Play Integrity that ship with Trusted Execution Environment (which is pretty much all ARM based Androids), Secure Element, and/or Hardware Root of Trust, but I'd appreciate if you have some significant exploit writeups (on Pixels, preferably) for me to look at?
> My concern is that future where banks can "trust the client" is a future of total big tech capture of computing platforms
A valid concern. In the case of smart & personal devices like Androids though, the security is warranted due to the nature of the workloads it tends to support (think Pacemaker / Insulin monitoring apps; government-issued IDs; financial instruments like credit cards; etc) and the ubiquity & proliferation of the OS (more than half of all humanity) itself.

Hi, you don't have the break the control on the strongest device. You only have to break it on the weakest device that's not blacklisted.
The situation is getting better as you note, but in the past the problem was that a lot of customers have potatos and you get a lot of support calls when you lock them out.

I agree with you on the need for trustworthy computing. I mainly disagree on who should ultimately control the trust roots.
> Insulin monitoring apps
A monitoring app doesn't even interact with systems you don't own. Just put a liability disclaimer for running modified versions.
> warranted
Decided by whom? And why is Google trusted, not me? At minimum, I shouldn't face undue hardship with the government due to refusing to deal with a third party, unless we first remove most of Google's rights to set the terms.
