I tend to agree with you here. This is the equivalent of that scene in Better Call Saul where Jimmy makes a commercial without getting sign-off from the partners. It doesn't matter whether the thing worked - this is essentially a mutiny from the product roadmap.
Love Better Call Saul :) The comparison is not even wrong (in the Pauli sense). Required knowledge seems to be DevRels role within Google culture. The absolute last thing this was was “mutiny” from a “product roadmap”. They’re sort of just around to build things to help devs and evangelize. They’re not tied to roadmaps or recruited to work on them.
