Where are you getting the data on who uses what?

Self-reported, vendors' own websites, and a variety of other sources.

How much of that data is collected manually vs. automated tools? (I ask as the author of https://github.com/jpf/domain-profiler/ and someone with a casual interest in such things)

It's about 75% automated.
