No idea. I don't know when he last updated his website, though, I don't
think he has any bias against info from either list

Gunther's site, I can assure you, is not a catalyst for device driver
development.

In addition, I think perhaps you have a misconception about the number
of people providing development. To be clear, there are very few.
Consequently, there should be no mystery surrounding the motivation to
write device support --- as such motivation could probably be summarized
as follows:
- having an interest in doing so ... perhaps based upon personal
ownership of the device or just the general enjoyment/challenge of the
coding
- ease of adding support .... both in terms of coding complexity and the
time required
- and occasionally through contract

By in large, "interest in doing so" stands out amongst the others. If
there were a greater pool of developers, it stands to chance that there
would be a wider base of interest and, hence, a greater amount of
devices that end up being supported.

While the fact that two devices (one supported, the other not) have the
same components can be of great assistance to the development of support
for the latter device, it still does not guarantee that such support is
easily obtained. There may be factors which are dissimilar between the
devices (i.e. firmware, GPIO etc).

Second, developing support for a device not in personal personal
possession can be rather difficult. You'll have to find a developer who
is willing to work with you under such conditions....or, take that
initiative yourself.

There is no bias. What you are observing is solely a consequence of what
I discussed earlier:

- There are few developers.
- these few developers work on things which interest them personally

Find Asian developers with interest in such devices, and you'll likely
find support will follow. Otherwise, it isn't going to appear on its own....
