The trouble is that sciencia potestatis est only interdum.
Your employer, or the state, or similar is almost certain to be in a better position to do unto you than you are to do unto them; and (as we have seen all too frequently with police shootings, egregious fraud, etc.) even incontrovertible evidence is converted into penalties at markedly different exchange rates for different people.
If The Man is up to something so egregious as to be totally impossible to placate even the loyalists, then your sousveillance capabilities might actually ruin their day. Unfortunately, that level of egregious tends to be pretty damn high. The standards will not be so high when it comes to rightsizing the human resources.
This isn't to say that evidence isn't better than invisibility; but unless you have a commendably low-impunity environment, even perfectly symmetric surveillance capabilities will weigh heavier on the lower rungs of the totem pole than on the higher ups.
