OSI Asks Microsoft to Change the MS-PL
Xenographic writes "The OSI has identified two significant flaws in the Microsoft Permissive License, and is unlikely to approve it as an OSI license in its current state. Specifically, the OSI is worried about the way the MS-PL is incompatible with so many other OSI-approved licenses and how misleading that makes the term 'permissive' in the license's name. Now the ball is in Microsoft's court and they can choose to amend or withdraw it from consideration. From the article: 'The MPL is also particularly restrictive, and is uniquely incompatible with the maximum number of other open-source licenses, [president of OSI Michael Tiemann] said, noting that in its examination of license proliferation, the OSI had encouraged experimentation with license terms to encourage new ones to be written that were better than what currently existed.'"
Why isn't there a chart of the various licenses ranging from least restrictive to most restrictive?
That way it would be easy to show where a new license fit in and whether it was actually needed or whether it duplicated an existing one.
It would also show gaps where licenses do not exist right now.
And best of all, it would allow you to draw a line and say "anything below this line is compatible with the GPLv2 (or v3)".
As the various laws change, the chart would have to be updated. But it would solve this issue with Microsoft once and for all.
The MPL is incompatible with the MPL (Mozilla Public License) too. :P
And, wonder what happens if it is used as a dual license option with BSD

If you quit being an ass and took five seconds to look for yourself
If you quit being an ass and took five minutes to read the GPL, you'd discover that the GPL is incompatible with all open source licenses.
Why you ask? Because the GPL requires that all portions of a GPL-ed program must be distributed under the GPL. Hence, if I want to incorporate code that is under the BSDL, (Apache License, or Mozilla, etc.), and distribute my code under the GPL and let others too, I can't do that (unless I own the BSDL-ed code). That's why GPL is called a viral license and that's why it's fundamentally incompatible with most open source licenses.
That negligible aspect you refer to doesn't make GPL3 anymore compatible than GPL2 was. The key aspects are still not compatible.
GPL and other govern only distribution not usage. Here is relevant part of GPL
This License explicitly affirms your unlimited permission to run the unmodified Program.
As a developer, I wouldn't touch a license that doesn't cover use. The disclaimers of warranties and limitation of liablities are an essential part of Free software. The GPL fails to bind the user to agree to the disclaimers and limitations and thus makes the developers and distributors subject to liabilities (because these things are implied by default under applicable laws).
