How Bill Gates Denied Access to Office File Format Documentation to Stifle Competition

Summary: Microsoft's former chairman shows the company's attitude towards accessible file formats and competition

IT is interesting enough to know that Microsoft deliberately makes its documentation deficient and unavailable (the word "undocumentation" is actually used internally), but to know who is responsible for it is even more interesting. Comes vs Microsoft Exhibit PX03104 (2000) [PDF] provides an answer which fits the pattern seen in other E-mails.



We’ve recently change the policy for distributing our file formats, at the request of BillG. We used to be fairly lax about giving it out to pretty much everyone who asked for it (Excel even published a book through MS Press).

Our new policy (for Office2000) is that there are restrictions on use (can’t build converters, can’t be a competitor to any of the apps, etc). We required a signed license agreement in hand before we’ll send them the docs. They have to tell us who they are and what their company does, as well as their intended use.

Once we get a copy of the signed agreement back, I sign for Microsoft, and we send them back a hard copy of the agreement via snail mail, and send them the docs via email


This should not be particularly surprising. See other Comes vs Microsoft exhibits that we covered in:



For the investigative, there is more in our Wiki. The full text from this latest exhibit can be found beneath. It is particularly valuable to those who study Microsoft's reluctance to support open standards, let alone permit other office suites to inter-operate (free of charge). Based on the correspondence below, Microsoft deliberately targets possible competition and hinders access to vital data if the competition is serious. Shouldn't the European Commission take a look?

Hi Norm,

I don't know how urgent this project is--is someone covering the file format distribution in Tim's absence?

Hello.

MS-PCA 2545864 HIGHLY CONFIDENTIAL




As you may know, Visio is now a Microsoft product. We recently completed the documentation of the Video file format and we want to distribute it in the same manner as the Office docs are distributed. I know that there is a page on MSDN that tells requestors to e-mail this alias and ask for the Office documentation. Do you require that they supply you with the details of what they plan to do with it? Do you make them sign any kind of agreement? Is the documentation stamped with "Microsoft Confidential"?

Thanks for any information you can provide me.
