The privacy argument doesn’t make sense to me. The addresses are already in Google Calendar. They don’t need to be saved into a different service to be viewed anonymously in Google Maps. You can already do it in Google Calendar for one event/address at a time.

Yes there are business/internal-politics reasons why some obvious features or experimentation doesn’t happen, but those aren’t necessarily good reasons beyond short term benefit to specific individuals at a company.

But I do think some of it can generally be blamed on large companies losing their ability to be nimble due to the inherent friction of the politics and logistics that build up as an organization grows.
