My only concern about this is that a lot of the technologies identified as "adtech" on that diagram just... aren't:* LinkedIn
* Vimeo
* Hootsuite
* UserTesting.com
Marketing != advertising. The overall point is really valid, but this is a dumb way to back it up.
It's bad enough to just take the ad-serving parts of the diagram he uses, which add up to hundreds of technologies (or use Ghostery on any news site).
