[talk-ch] Larger removal of street and place names derived from the GWR

The OSMF Data Working Group has removed roughly 9'000 street and 1'000
place names from the Swiss OSM dataset, because there is very good
reason to believe that they had been derived from address data from the
GWR (https://www.housing-stat.ch/) which at the time was not legal for
us to use and currently has the same status, more on that later.

Most affected is likely French-speaking and central Switzerland and
naturally mainly such names that are not easily surveyable (which is why
they were missing in the first place). Nothing was removed in the Canton
Berne as the GWR data for there is essentially the same as the cantonal
address data that we have access too.

The best course of action is simply to get off that couch and go out and
survey as far as possible what was "lost", it should be possible from
comparing http://qa.poole.ch/ch-roads/list-2017-08-01.html with
http://qa.poole.ch/ch-roads/list-2017-08-04.html to determine how much
your local area has been affected.

Quickly back to the current situation with the GWR. As you may know on
July the 1st the revised GWR ordinance entered in to force, unluckily it
seems that I was right in being skeptical in
http://www.openstreetmap.org/user/SimonPoole/diary/41672 as, as it seems
now, the main effect of the revision seems to have been to open up new
business opportunities for SwissTopo but even that will not happen
before 2020.

All in all this means that until further notice use of the GWR address
data on both the SwissTopo WMS server and map.geo.admin.ch (and most
other data there) is completely off limits.

Naturally additional political pressure on the federal counsel to live
up to their announcement
with real instead of Fake-OpenData is more than welcome.
