I don’t want to argue, I understand your position of trying to publish this data and being frustrated by the data being deemed not useful or in scope by other contributors.
I’m not an OSM expert at all — but I can guess that opening hours or phone numbers for a store that has no proper geographical location (and thus no geo-existence) would be perceived as not having its place in geographical database.
I suppose OSM is really a GIS (geographical information system) more than, for example, a tourist map, so it’s not totally absurd that volunteers would have issues with integrating data not properly aligned with the ideal way of working of a GIS (everything is geo-localized).
Google Maps has obviously diverging goals and incentives in that regards (serving ads, being an intermediate to stores).
As Google Maps and other online maps are trying to be many things, including the yellow pages, they probably don’t care about being an ideal GIS.
Open communities of contributors are often misunderstood when they enforce limits to contributions, and at the same time seek more contributors! But it makes sense when your success is defined on building a digital commons—scope and values is really what define the project, not much else.
(The Wikipedia community has to explain constantly that the goal is an encyclopedia, for example to people trying to use it for publishing their own findings, personal biography or fan pages. The Linux kernel won’t accept some driver contributions too.)
Of course it now seems that the OSM community of contributors is itself divided on what is the scope of OSM.
