I don't think this is a bold statement at all. I agree with you about "pretty consistently", but that is not consistent enough for many uses. Let's say I want my maps application to know whether a building is commercial or residential. Some buildings have building=residential, others have building=yes or building=oui, and others just have landuse=commercial (or landuse=residential, suburban, quarter, suburb, neighbourhood, or residential=yes, or residential=apartments). This is not the worst-case scenario; we can write an interpreting adapter for these tags. But somewhere in the world, there will be edge-case tags the adapter won't handle. And it is challenging to use that approach for applications that tens of thousands of users will see and scrutinize.

Zooming in on my hometown the buildings that I expect to be commercial are tagged as commercial, but on Google maps the same buildings are pretty inconsistently coloured. Are there other commercial maps that do a good job at that?

  I don't know off the top of my head. But missing tags or mistagging is a slightly different problem than tags that are difficult to parse. What's un/mistagged can be corrected in a crowd-sourced way (as Google Maps is doing). What's challenging to parse continues to be so no matter how much crowd-sourcing is present. The solution is straightforward for OSM - standardize the tags. It's been a long debate in OSM, but I hope the commercial influence will make them do it. There are practically no downsides and significant benefits.

  `building=oui` is wrong and was corrected.
