Google does not come anywhere close to this. Not to mention that only a few of them can actually approve and fix things.
And because google is closed it does not have any kind of Quality Assurance tools. In OSM you could easily check if the last edit changed the opening hours and if the new one is strange (like not open Saturday evening)
Your prediction fails to account for the fact that Wikipedia can manage the problem, and they are probably the most important information source there is while still being by far the easiest to edit. What makes you think it is impossible for OSM to do it?
(Also, a bit dishonest to call OSM irrelevant when it is the canonical data source for a number of famous application, including Apple, even if it's not directly applicable to the situation here.)
Once they do, it will have the same problems Google does, but worse because they don't have the resources to fight back.
It is much easier to fix mistakes than it is to fight an active adversary.
