I get so confused with product marketing these days and I am not even talking about product line names.
On the one hand I am supposed to read between the lines of a few technical sessions and perhaps an offhand remark in a blog post (oh, I think someone also chatted with someone else and noted it in GeoNet that theyheard if from a developer) and understand the details of ArcGIS Pro gretting major changes in licensing. Then, when one looks at the same sources of information (sessions at the vendor's conventions - Fed, Dev or Int'l) and information seems just as explicitly stated, whether it is SciPy in 10.3 or Anaconda in 10.4, I find out that I have gone to far.
Ultimately, the only thing that I think that I am sure of here is that nothing is sure and I am not even sure about that as I feel that someone will pull a rabbit out of the labyrinth in this thread that explains everything the way it was supposed to be understood if we stood in their shoes. I will remember to bring extra socks and band-aids.
