pf » Open Source at Adobe

I noticed this snip about open source software at Adobe on the O'Reilly Radar:

The Adobe chap had interesting things to say about their heavily constrained use of open source: they basically have a sandbox where open source is allowed but at some point between the sandbox and the Adobe core products, open source becomes verboten. Not even open source compilers, even when they don't link to open source libraries. Things may be changing, though: Adobe has its own open source projects now.

Interesting... I haven't seen that open source site from Adobe before either. The site looks like a bunch of common api's and libraries written in C++
