I'm worried that Poettering's new startup is designed to ban unapproved Linux, BSDs, etc.

The cynic in me says the Win 11 "you must have a TPM" push (along with passkey's "big tech owns all your accounts" design) were rammed through specifically to centralize control of the open web.
At this point, if the federal government actually forced OS-level censorship, most literate folks would just download Linux. So, first, they need to close the remaining door.
I'm not exactly holding a candle for debian. SystemD has already started adding support for this, and, in the past, downstream has been able to force unpopular debian votes through.
SystemD only added an optional birthdate field to userdb, and many distros don’t even use userdb by default. And there exist distros without SystemD. So I wouldn’t worry too much about the SystemD angle, although IMHO they were spineless for adding the field.
