Can the Fedora community afford to not support "Trusted" computing?
If someone wants it bad enough then they will fork Fedora and do it anyway.
Fedora can play a dominant role in its use, provide an environment for evaluating the effectiveness of the technology, support the education of the developers and users so they can keep their knowledge and skills up to date.
How to apply security updates these systems in a security controlled environment is an issue that will need to be addressed sooner or later.
Fedora should not turn its back on a technology because it may be misused. Would you turn your back on a dangerous animal? Somethings need to be understood even if using them is ill considered.
