Accidentally revealing your intelligence gathering capability is a famous trade-off problem. The Allies in WW2 occasionally had to let a ship get sunk rather than make it obvious that the Enigma had been cracked [0]. Plausible alternatives are usually assured to be in place, for example radar in the above case, or parallel construction in modern law enforcement.

Bigtech are likely increasingly careful about making it too obvious that certain technologies (for de-anonymisation and correlation) are in use. Most people will still believe in unlikely coincidences rather than sophisticated behavioural analysis and covert monitoring of audio systems etc.
