This is obviously not good, but I'm not sure it is particularly useful for something "important".
Any target of high value will be pursued and observed by trained humans with advanced tools. The amount of data collected, I suspect, would be less but more accurate.
A device like this just lowers the bar (really low) on tracking. However, it increases the noise/inaccuracy. If combined with some key logger and other devices, it could provide a very detailed picture of someone's communications and movements. But it would include a lot of noise as well, which would still require a lot of sifting and organizing to make sense of the data (and especially to filter out the noise).
If anything, I think these devices are more a money grab on the "spies" than a significant intrusion on the targets.
