That's probably a misrepresentation. They don't like the mechanism used
by the current YWMS plugin because they believe it sets a bad precedent
that pushes at the edges of their acceptable use policy.

What you can put on the wiki isn't really relevant.

If you don't want to use the imagery, don't. In the same way that if you
 don't want to use a Garmin E-Trex GPS because it doesn't run free
software, you don't have to. You can still use npemap or Landsat, or
your own linux based open source GPS tracking tool.

That doesn't mean you should seek to stop others using the Yahoo images,
just as Linus wouldn't complain if I used MS Visual Studio to edit the
kernel, and sent him a patch that I wrote using it - he'd just accept or
reject the patch on it's merits.

Would you tell me not to contribute to OSM if I bought some aerial
photos on a license that said only I could see them, but I could derive
data from them?
