I'd like to argue that for a project which is aimed to be open and fully published and shared; you should not care if this qctivity is "spied" by the NSA; at least if ou live in most countries; unless you have shared publicly to OSM some national secret or personal information unrelatd directly to the mapping activity in the public project.

In fact we are open to "spies" and copies or archival of our data and public discussions by anyone :

The only concern is if you are contributing to the project using an hidden personal identity under a pseudony, because you would not share the data if you were contributing with your personal name, or because you don't want to reveal your moves in your country, or associate some public interest with your own identity (e.g. sharing some info about industrial pollution, or LGBT activities and lobbying, or your religion, or political opinion from a place where it is dqngerous to expose it or if you have contats or regular trips in such country).

If you live in a country where all this activity is legal and protected by law or constitution, and freedom of speech is not severely limited, every activity you in OSM while respecting the controbutor terms, licences, and reasonnable etiquette when speaking to someone else via the public discussion channels; and don't stole data you are not permitted to copy, you should be proud of contributing and you should never beware personnally of spies looking at your activity. However you should just care about protecting the common project itself in a collective sense so that what you contribute will not cause personal problems to others (personally or collectively); discussions channels can be used to decide collectively what to share or not in those data to help define some common policy (which may need to evolve over time due to possible new threats). We don't run OSM to create new threats against people, but to help them.
