Thanks for the feedback!
I'll add better descriptions next time!

I don't agree on the address. Defibrillators are referred to (on website, FOD list, ...) with a name (often the building they are on/in) or the street & nr. Adding them to OSM makes referencing between lists possible and/or easier.
Re-use of the OSM-data in other websites, including the name and address, makes retrieval in case of emergency easier.
