Steve Loughran writes "The ASF board have put up on the Apache Web site, a page
rebutting claims that the new ASL2.0 license is incompatible with the GPL, claims made by on an
FSF page and covered in
Slashdot last week.The key points are (1) The interpretation of the GPL license is not just the opinions of individuals in the FSF, it is designed to be rigorously defendable in a court of law.
(2) Rather than look at opinions about compatibility, people should look at the
ASF2.0 and GPL licenses to see if they really are compatible.
(3) If you look at the two licenses, they really are compatible.
This means there is nothing to stop you linking your [L]GPL apps against apache libraries, shipping them with apache applications, and the like."
Of course, this is still up to debate.
