Hi, about facebook.

You're not entirely correct about facebook. It depends on what on facebook you use. I suggest you join the legal talks OSM channels this has been widely discussed before and the consensus is very clear.

Indeed even FB themselves are very clear on this matter.

Photos published on facebook can't be redistributed as they're copyrighted and the photographer has the ownership/intellectual property right always. Even parts of photos are protected. 

However data on photos published on facebook or anywhere else - as facebook themselves very clearly somewhere in their huge FAQ explains is not protected by this! If you see a lamp post somewhere on a photo in FB that data that the lamppost is there is not covered by either intellectual property rights of the photographer nor by Facebook.

Facebook is very clear on that, that this data on photos, while the photo itself is copyrighted and protected, the public data visible on a photo is not.

Feel free to browse through the huge FAQ of FB and learn about this little nuance or join the legal talks where I raised this question 3 years ago and the unanimous consensus was back then that FB is right - public data visible on a photo on FB is not copyrighted, only the photo itself is copyrighted.

As for the other tags... I must have automatically added the "fire_hydrant:" in front of all the tags. Usually I work very consistently so if OSM demands us to map inconsistently I sometimes forget such little issues ..

will try to be a bit more careful next time to not be consistent when mapping but map inconsistent where applicable :)

Thanks for pointing this out.
