I understand completely your viewpoint.  However, let me point out that one of 
your key objectives should be to
increase popularity of GNU Radio software.  One way to do this is to encourage 
and support GNU Radio software examples
that interface with MATLAB in some way.

There is no denying that 1000s of developers are using MATLAB as a tool to 
develop radio and other RF applications. 
I'm active on MATLAB lists and forums, and besides commercial developers, I see 
literally 10s of student questions
about RF projects every day. OFDM, MIMO, xxSK, you name it... Professors have 
assigned them to do it.

If you can draw those developers and students (and Profs) into the GNU Radio 
environment and introduce them to what
you're doing, it will only serve to further your goals.  However distasteful 
from an ideological standpoint, I might
suggest to take a page from Bill Gates:  add low-level compatibility for 
"other" RF software to GNU Radio software
(typical examples such as transfer data, call MATLAB functions, MATLAB-callable 
functions), and eventually the
"others" will discover how much better, well-supported, and dynamically growing 
is your GNU Radio software.
