Well as I said, some of the points were covered.

The difference in scale is appreciated, although there is obvious scope for
mappers to enrich open tree data significantly. There other major
difference is one will typically about conflation and the other about
importing (leaving aside planned updates).

Petrol stations are probably one of the POI features with the highest level
of completeness in the UK (6,999 on taginfo vs. 8455 estimated for end of
2013). The taginfo figure is a slight overestimate as it includes some fuel
for canal boats and oddities like hydrogen sources. With well-mapped
objects like these, there will have been significant input from several
mappers: inferring that these objects have come from a 3rd party data
source, rather then having been updated from it would be erroneous. So I'm
fine with adding source on new elements only.
