I agree and that is why I would not suggest switching to BSD.

My suggestion would be to license Blender as "GPL with exception for

All this means is that the GPL would not automatically apply to extensions
and so
extensions would have to be explicitly licensed with whatever license the
author choses.

This way commercial companies would be free to make closed source extensions
charge for them, and open source developers would still be free to make open
GPL extensions.

Right now, all extensions are automatically forced to be licensed as GPL.

But just to be clear, I am not talking about the code for Blender itself,
Blender itself
should always remain GPL, it is only in the matter of extensions that I
think authors
should be given more freedom to license extensions how they decide is best.

When Blender was given freedom, I do not think people wanted to take away
the freedom
of people who in the future would write extensions for blender, but nobody
thought about
that at the time.

Right now Blender is closed off from a potentially lucrative market because
of its licensing.

Licensing blender as "GPL with exception for extensions" is what is needed
to open up that market.
