Keeping your jurisdiction small means you can do more within that jurisdiction, by ignoring even important problems that are outside it.
But the alternative is ineffective doomscrolling because all the world’s problems are yours.
It's just that practically nobody in the world can credibly demand Google's board, or even just upper middle management, to make a decision on small matters.
When a ticket reaches your average IT guy, they can't usually delegate it to a lower tier employee unless there are formal support tiers, like L1 and L2, and the ticket was sent to one of the upper layer techs (which usually doesn't happen straight away, because of how L1 and L2 support teams work).
If this is not the case, the only way out is forwarding the issue to another team.
Sorry guys, that’s another team. They’re extremely reluctant to deploy even very important things. Separation of responsibilities means we have no other choice.
