alt Hacker NewsTo clarify, regarding the confusion: it was disabled, leading them to think it didn't outright exist.
Why disabled? Well, its performance is apparently quite poor. But why?
...Apparently to save money.

The thread made it sound like it was more- that the actual release of pixel 11 did not have the firmware to support MTE, not that it was just disabled.
Is the thread wrong or did I misread it?

No evidence of this is presented.
The performance isn't really that bad but it's definitely a hit. The bigger issue is that it causes apps and services and occasionally also the kernel to throw MTE SIGSEGV which becomes a substantial problem if the developers for said apps or services don't care enough to fix them.
So the TLDR is that the main issue is that it causes a whole bunch of stuff to segfault when bad memory accesses occur but where they wouldn't segfault without MTE. It makes the phone feel unstable to average users since stuff just crashes with no real end-user-facing explanations.
