I think that's a touch unfair. The fact that Debian runs on the BeagleBone Black and RedHat doesn't puts a bit of lie to that statement.
If ARM became a big platform for servers or workstations, RH would probably roll out a ARM variant within the week (could be they even have test versions floating around their internal network).
In particular as Fedora already have ARM versions across the board.
Red Hat has no reason to care about platforms like BeagleBone Black.
My comment was more the fact that Debian has enough excess resources to support the Beaglebone Black. So, categorizing Debian as having barely enough developers to support itself is disingenuous.
Nonetheless, Red Hat really is doing a lot of upstream development, certainly more than Debian does as far as I know. Indeed, the Debian community has managed to keep their release schedule and meet their goals lately, so they're probably in a better shape than "barely enough to support itself", but there hardly seems to be room for comparison between the two.
By comparison Debian just has enough resources for keeping Debian running. SUSE seems to be an afterthought at this point. Ubuntu seems to mostly be concerned with itself.
