Heh, look at the script that they're loading.

You can tell by the URL path (it's under /content/dam) that it's served by Adobe Experience Manager (Adobe's CMS, dam stands for digital asset manager, where you store static assets like images and js). The script itself is "target.js", which is Adobe Target - their A/B framework - which "supports custom code insertion"[1] similar to a tag manager.

It's not GTM, but this is like loading the GTM script itself from archive.org.

It's worth noting that AEM is often very badly set up, following requirements from managers who have no idea or concern about web development, and later maintained by low cost content editors who barely know some HTML. Moreover, this CMS seems to be a standard for big sites even though the licenses are costly, development is slow and complicated, and it adds a lot of human hours to the site maintenance.
