I'll bolster it. I've worked on a site-you-have-heard-of. They were struggling and as a response they would change marketing leadership basically every year to try to find a new way to reach a new or different demographic. Every year the new marketing leader would say "we're not doing any of that previous idiot's strategy, as I am the one who knows best". And as each marketer tried to make their mark, 50 new Google Tag Manager script injects would appear.

Now, whose job was it to remove the previous 200 Tag Manager scripts? Obviously the last guy's, because those were his experiments and he was in charge at the time so new guy was clearly not responsible for it. And at the end of the year, 250 Tag Manager injections would now exist and we would turn the page to reveal a new CMO.

And thus ends the parable of how I put a wrapping feature flag on the code that added Google Tag Manager to the site so that I could display the effects of the insanity and demonstrate why the PageSpeed metrics were ass and why engineering couldn't fix it (in a way they would permit, anyways).
