I've work for large national ISP where they are heavily trying to create a new series of network engineering tools (device discovery, adding new ARs with ease, upgrading existing devices, pragmatically change thru-puts between regions based on load, etc).

Most of the backends for these types of tools would explicitly be done in Java. Why did they chose Java? Mostly because they would staff entire teams with H1Bs and dump them after 5 years. The directors of these projects would only hear about "buzzwords" surrounding the latest tech if they themselves went to conferences or happened to luck out if the project managers they hired had varied experience.

Oddly enough, there's a lot of greenfield work being done using Scala at Verizon and Comcast. But from my direct experience, it's entirely dependent on the team. The more the team doesn't rely on contractors the more likely they are to use niche tech.

Second that. Even the much advertised linked in uses Java engineers much more than NodeJs
