MS Accused of 'Excluding Free Software' from Licensing Scheme

Here we go again...

Microsoft's licensing terms for its Windows server protocols explicitly block Linux, Samba and other projects covered by the GPL from taking part, according to Carlo Piana, a partner at Milan law firm Tamos Piana & Partners, which represents FSF Europe. ***

The licensing terms don't stop an open-source developer from creating a separate component, under a proprietary license, that implements the protocols. ***

A Microsoft spokesman said the licensing terms are not discriminatory. "The same terms are offered to everybody, including the makers of free software," he said.

Is it discriminatory to have GPL-incompatible licenses?
