A bit hyperbolic dont you think? Even if you disagree with the politics, you'd agree that updating a random restaurant's opening hours is different from updating a national landmark.
For instance, I checked Nepal area and Google Maps already shows the area as flood affected. It didnt take years.
GMaps can be extremely slow when it comes to responding to user reports, or updating regional info like road networks or new subdivisions. A lot of that comes down to the fact that Google relies on government entities for authoritative information, which can mean waiting months or years for the local government to provide new info. The federal government updated this one quickly.
In my local area Google Maps is still missing some rather crucial elements of a high-throughput road, which were added to OpenStreetMaps almost two years ago.
