Why Non - Pharoing companies should support open-source?

Dear ESUG members, 

Some of you may have miss my talk from ESUG. My point is important for the future:

I motivate that even if you do not develop in Pharo it is important for you (and the complete community) to support a 

strong open-source movement.

Check http://consortium.pharo.org

"Why Non - Pharoing companies should invest in open-source?"

I hope that this will convince you to support the good energy and the work we are doing since more than a decade now.

Feel free to contact me.
