A) THE SHORT VERSION
WARNING: Running OONI may be illegal in your country, or forbidden by your ISP. By running OONI you will connect to web services which may be banned, and use web censorship circumvention methods such as Tor. The OONI project will publish data submitted by probes, possibly including your IP address or other identifying information. In addition, your use of OONI will be clear to anybody who has access to your computer, and to anybody who can monitor your internet connection (such as your employer, ISP or government).
I would strongly advise against this kind of wording. It reads like hackers trying to CYA and also to settle some kind of long standing argument, without considering real world impact of *those* statements. Advocating for somethign that may be illegal is at best, a CYA but at worst, actually setting people up for massive problems.
All the best, Jacob
