How so?

I believe that when someone distribute something that is dual-licensed he
has three options:
1./ Distribute it under MPL
2./ Distribute it under GPL
3./ Distribute it under Dual License MPL/GPL

And I believe that in any case you're entitled to the eCos source code.

Same kind of thing goes for eCos license. If $SOMEONE gives you eCos source
code after introducing some pure GPL code, then the whole thing become GPL.
So its now illegal to use it under the eCos license. 

Actually I think one could just take the eCos  source code, and make it pure
GPL without even including any other code.

Hum... now that I know the evil plan i wont be scared anymore. :)

Hehe... thats an argument for the GPL, but not one against a dual license
that also has GPL in it.

I think it is preferable when people know exactly what they can do, but in
the case its impossible for them (eg in the gray areas) I think I would
agree with you.
