Typically the person including the JS tag that then fetches the massive third party payload has no idea that's what is happening. It is very common to get multiple departments and contracted companies sticking their misc JS in since every marketing SaaS tool they use has it's own snippet. Your SEO guy wants 3 trackers, your marketing has another 5, and you sell on XYZ online market and they have affilliate trackers etc. No devs engaged at any point and the site performance isn't their responsibility. They can't do their job without their snippets so the incentives are very sticky, and the circus goes on. It's kind of like an NPM dependency tree of martech SaaS vendors...
