That exoscale screenshot is very similar to what I see with NoScript on a 100 Mb/s connection before I temporarily allow their JS.
What's nice about NoScript is that I can turn on their JS but keep turned off the JS scripts from the other sites. Apparently they only use googletagmanager. Ublock doesn't report any blocked script so it's a rare well behaved site.
Google tag manager is sometimes (often?) used to load every other third-party script, so if you allow gtm to load you'll probably see a bunch more scripts. As a web developer, gtm was the bane of my existence because marketing could change and break the site significantly, while decreasing user privacy and page speed, and the devs could take the blame.
