The noise I've heard about FinFisher has been less about its use in Western countries, and more about Gamma selling it to oppressive regimes that use it against protestors.
If your goal is to keep your calls away from Egypt's State Security Investigations Service, by all means use metro Skype. If you're trying to hide from a country with law enforcement access to Skype's backend, then don't. But I don't see what the latter has to do with FinFisher.
As far as recording things from the mic outside of Skype, if FinFisher does that you're probably toast regardless. I haven't dug into the technical details, but I've seen it mentioned that it can deliver arbitrary payloads. Someone who reads through the doc dump will hopefully be able to confirm what exactly they've been doing with it.
Yeah, most of this finfisher stuff appears to be for surveillance states (plus assholes like nsa), not real law enforcement. Real cops / fbi can get a warrant and go straight to microsoft who appears to have very good skype capture ability. Why would you screw around with all this nonsense when all it takes is a couple hours of a DAs time to draft a warrant, a trip to see a judge (assuming you have a reasonable cause), then a fax to microsoft? Unless of course the reasonable cause thing is tripping you up...
ps -- that's not to say our governments aren't well aware of what FinFisher is doing. I bet the fastest way to seriously piss nsa/various pigs off is to sell an exploit before sharing it with the US/5 eyes. I mean, they don't "know know", but they know, the same way we know damn well what goes on in extraordinary rendition, though we all run around pretending to be shocked, shocked! that there's torture in egyptian prisons...
