This is an accurate and interesting statement, and I am glad you made it.
Yes, the Linux policy has been to expand, gain market share - you can see that
in breathtaking kernel development, user space frameworks and applications, and
also those couple of hundred Linux distros.
As a result of that, security was not the primary concern, willingly or not.

Perhaps it is time to change that, exactly because the critical mass has been
reached in the computing market space.
Fedora has millions of users.

You have to start raising alarms when things as described here in this thread
are tolerated.

Linux, My Dear, the honeymoon is over !

You have been our princess and enjoyed it. But now the reality bites and we
have to bite the bullet.
Security is an issue; it has always been, as you say, and for that reason has
to be addressed as a product release policy.

The end users of F15 are at risk.
They should be fully advised what's the danger with this product.
After all, it is an open-source project.

The issue is serious, because it raises not only technical questions, but also
internal (Security, QA, etc teams) and policy ones.

Sorry about crashing the party ... I was just feeling lonely and had to find
a soul or two ... and the lady at the door told me there was something going
on here, but she was not sure what :-)
