They would know loads about the empire's movements from watching them. The Zerg apparently have FTL connection to their probes, so they would be aware if any were captured or lost. The Protoss do not possess psychic disruptor technology or they would have used it against the Zerg or each other. Which they logically should have, but whatever. Jamming the telemetry of a couple of probes doesn't solve the other problems.
In fact, combined with the Confederacy's rapid development of psychic warfare, Tassadar capturing probes may have contributed to the Zerg invaders going berserk at the end of 2499 despite spending the previous decade almost lazily expanding.
