The OONI Probe application, while offering the ability to measure internet censorship and network performance, relies on user participation to generate its dataset. Users must download and run the software on their mobile or desktop devices to contribute. The effectiveness and comprehensiveness of the data collected are therefore dependent on widespread adoption and consistent usage. Furthermore, the publication of test results, while intended to increase transparency, could potentially expose users in certain regions to repercussions if their government actively monitors such activities.
