The old kernel development model was much more third-party developer
friendly in this sense. It used to be that even minor version numbers
(2.4.x) were stable in this sense and odd minor numbers (2.5.x) were
not. Then a distro could include the even ones and developers could
rely on the API and ABI until the next even release came out. In the
meantime, they had time to adapt to changes being made in the odd
releases. The odd releases were generally made available by distros for
testing by the stout of heart.

Keeping up with rapid API/ABI version changes is a burden for any
third-party developer, not just proprietary ones. Having to go back and
continually modify older code for compatibility distracts from
development of new features. It also introduces these delays where
users can't move to new kernels (which might include critical security
fixes) or must forgo their third-party codes until their vendors catch
up.

Les's argument here is that it's hard to get the latest application
software without committing to live with the instability at the kernel
level. RHEL5 is still shipping Firefox 1.1.5 AFAIK, and equally ancient
versions of other applications. That may be fine for enterprise
managers, but many single users and developers would like to be able to
keep up with application and toolchain advances.
People talk about TCO and point out that there's lots more application
software bundled with with a typical Linux distro than with Windows.
That's all very good, but unbundled applications have the advantage that
the user isn't tied to the bundled release of the application if they
want to stay with a particular version of the system.

Some of us accept it--or even welcome it--for some things but find that
it's a burden for others. There's no reason not to consider changes in
policy that would address some of the disadvantages of this situation
without doing too much violence to the advantages.

I don't mind dealing with the need to go get third-party software from
third parties. One has to do so for Windows as well. The set of things
that one needs to get from third parties in order to have a system that
performs most of the common tasks a user expects is just different.
But there seems to be an attitude on the part of some people in the
community that the best way to pressure vendors of proprietary software
to open their code is to force users who need that software to suffer
without it. I think that alienates users and is counterproductive.
