I think we have some models of what would happen to Go without Google, it's probably similar to what happened to Java under the weaker period of Oracle's stewardship.

The tool as-it-is keeps chugging along pretty well and even improving in small ways, but it stops reacting to larger trends and misses the boat at critical moments. Some new language in the same space comes up and finds it easy to shear off a massive portion of its user base by doing "the same thing, but modern".

(Less obvious models would be PHP to backend JS, and PHP and Python to Go, which had similar community development arcs.)
