So Microsoft will open up with information on many protocols/formats, and provide a “covenant” not to sue open source developers. Note the exception. Microsoft reserves the right to sue companies who commercially distribute such implementations. They need to get a license. As Microsoft put it in their principles:
Open Source Compatibility. Microsoft will covenant not to sue open source developers for development and non-commercial distribution of implementations of these Open Protocols.
As far as everyones reaction to this, Arstechnica wins with the best quote:
“Instead of offering a patent license for its protocol information on the basis of licensing arrangements it knows are incompatible with the GPL—the world’s most widely used open source software license.”
It may settle some curiosity in regards to how close certain reverse engineered implementations are to the actual protocol, but beyond that I don’t think it will make any difference. I think this caveat would limit most projects ability to utilize the information. I don’t think any major project is willing to utilize code subject to that limitation.
For example I mentioned just the other day that Exchange compatibility would bring about the most corporate adoption to Mozilla Thunderbird. Well this could potentially help make that a reality, except Mozilla’s commercial arm would be subject to trouble come release time. Not to mention any downstream commercial distribution that includes it (including many Linux distributions) unless they include a version without this code.
It may however be possible for a company to sell a product and offer a GPL licensed open source “plugin” or “addon” that adds the functionality. So for example Thunderbird would ship as usual via Mozilla Messaging and various Linux distributions. If you wanted exchange compatibility you would need to go to mozilla.org and download the addon for it. Similar to the current process for the provider for Google Calendar. However this adds a nasty extra step for users. It’s far from ideal.
The other notable thing in my mind is this part of their principles:
Industry Standard Formats. Microsoft supports many data formats promulgated by standards bodies in its products today. We will apply Principle II with respect to any standards-based data formats in our high-volume products. We will incorporate customer advice from our Interoperability Executive Customer Council and our ongoing community and customer engagement efforts to give us guidance to prioritize which standards we support in any given product release.
We want OpenDocument.
So despite all the media attention, I don’t think open source gained much today. There’s potential (OpenDocument getting priority would be nice), but really no big win. I just don’t see projects giving up GPL, and I’m pretty sure this agreement would violate GPL.

Yes, “non-commercial distribution” kills it, they know it for sure, so this move is a joke globally.
Ah! so it’s with respect to this announcement that they thought their quietly misogynistic superhero anthropomorphisations would make them look better.
