The Wikileaks press conference announcing JA had been "spied on" was very stupid.
Ecuador didn't need the headaches or expense and probably decided he was a nutjob.
Of course they were eavesdropping - he was living in their embassy.
You know where a country's spies are based, right?
That would be primarily in their embassy.
If you want privacy from a country, Step #1 is: FFS just don't LIVE IN THEIR FUCKING EMBASSY.
