Anyone is encouraged to take part, as a user and/or contributor. It's base is OpenStreetMap, so the data-usage is allowed under a copyleft-license, which make the project a possible base for new or extended projects itself. There is no company behind all this, but a non-profit organization. Its not under jurisdiction of the USA.
But still: Beware of possible trackers! At first sight I noticed buttons to like or tweet, from two of the major "social" networks. And they state the usage of analytics tools by a major search-engine. (Meanwhile there are maybe more or less of them, because of the GDPR.)
