I've really come to dislike Google over the past decade or so, but I do like that their Speedtests, Lighthouse etc don't hide this fact from you.

Pretty much all sites I've been asked to look at were getting low scores because of Google Tag Manager, Adsense and the like. It has a very measurable impact, and yeah, removing it speeds up the page.

The environmental case will probably not fly for regulation, but it just might in public shaming of large companies. "Hey, $company, your usage of $trackingTech uses as much power per year as an average family of four. Is that really in line with your green approach?"
