Because many people want to run something Linux based, or just
something that is free software.

2D-only support is better than no support.

If they can sell it, they will build it. There unquestionably is a big
market for graphics processors.

My understanding of graphics driver development is quite limited, but
I believe it is many orders of magnitude less work to have the basic
2D stuff work, when compared to writing a complete OpenGL
When there is a working OpenGL available, it often makes sense to use
it for 2D graphics, too. On the other hand, one would first need to
have such an implementation available.

There mostly are only few different graphics processors available. At
least my impression is that all the modern ATI GPUs are very similar
from the perspective of a driver developer. I believe the situation is
quite similar on Nvidia side, too. At least the nouveau driver support
has been quite similar for a very wide range of different Nvidia GPUs.

For the reasons I wrote above, I believe this is actually not a very
sustainable way forward. It seems the existing support we have is
easier to port to new devices than it is to write a complete high
performance OpenGL implementation. On the other hand, spending effort
on supporting a wide range of hardware where possible still allows
many more people take advantage of free software. Work on higher end
features seems also take place, but I guess the progress there is a
lot less visible due to the vastness of effort required.

There exists the Open Graphics Project:
http://wiki.opengraphics.org/tiki-index.php. They are developing a
completely open graphics hardware design. I have not followed them
lately, but at least the site seems still quite active.
