Re: IBM is to FOSS as oil is to water
Apache & Postfix are from IBM?
I couldn't swear it but I'm pretty sure both were released as "EWS" and IBM may even have had a hand in setting up the Apache Foundation. It did have a fine tradition of releasing stuff it didn't intend to pursue commercially: EWS was all about absolving IBM of any liability.
I think the problem now is that just does a lot less research and is less savvy than, say Google, in getting developers to work on Watson than TensorFlow.
