Personally speaking: Relying too much on 3rd parties (especially from companies like Google that have a history of removing systems) can break things. Design your systems to be resilient and standalone as much as possible.

Meh. Those technologies are poor examples of your point, imo.
The Angular 1 / 2 situation is a great example. The Rust over Go is some advice based on the lesson learned.
