I'd like to distinguish between *monitoring* Wikipedia for changes that could affect PR, which is fine (so long as they don't put unreasonable loads on WMF's technical infrastructure), and *editing* Wikipedia in a way that breaks any number of community rules and/or the WMF TOS. If they were monitoring without editing, or were editing in ways that were compliant with our policies around disclosure and handling COI, that might be manageable. However, if the reports in this thread are true (I have not personally verified them), then that's a big problem. I am adding Legal to this thread, but in general my view is that they WMF pays almost no attention to enforcing the TOS regarding COI issues, and I don't know whether they will do anything about it in this situation. :( I wish that they would get energized about COI enforcement.
