Adobe makes more than Flash. They have a number of user tracking, profiling, and A/B testing systems, plus an email delivery and segmentation system. Some or all of those things started as Omniture. Google also has Google Tag Manager, which is a third-party JS for injecting more third-party JS. When half your site's content is loaded by Adobe into "mbox"es, triggered by JS loaded by Google Tag Manager, it's a nightmare for real developers and end users alike even with everything working.
