I'll just say this. Saying 'of course' that an obscure OSS OS (and yes, OBSD IS obscure, and anyone not being emotional should be able to admit that) having full hardware support is silly, when so many similar OS projects still don't have support for much hardware.
Besides, TPM is at version 2 now which was announced in 2014, so where is the OBSD support for TPM 2.0? Why does it not support it?
Saying 'of course' it supports it was indeed silly when it doesn't support the more recent spec which is still 9 years old and isn't backwards compatible...
