While I have no problem about probes doing wifi measurements too, I do recognise the problems especially the commercial vendors might have. People could use the probes to determine if sales-claims was correct ("our coverage is xx%"). The answer, however is not to avoid current probes doing wifi analysis, but to make sure only mandated wifi networks can be chosen for test. The problem about the validity of wifi-analyses using current probe (especially current probe installation) can be solved only by opt-in as care should be taken to install the probes in a user-like environment.
