There’s more tooling for non-professionals to keep a leash on desktop app network usage, too, like LuLu[0] and OpenSnitch[1]. There’s ways around these tools as there is with anything else, but it raises the bar a bit since the user is unlikely to let random programs connect to servers they have no good reason to connect to, once made aware that the attempts are being made.
It’s not as reasonable for the layman to do this on the web, since it’s par for the course for a single visit to a big commercial website to kick off connections to dozens of unintelligible domains, and to sometimes break if these connections aren’t allowed. OS-level tools like LuLu aren’t of much help here because significant limitations on the servers a browser can connect to essentially break the browser, which leaves you with extensions like NoScript and uMatrix which for the explained reasons aren’t as straightforward to operate.
