I get the impression that some aircraft commanders are of the opinion that leaving "Mode C" off is a good way to avoid detection if they infringe CAS by accidently departing their cruise altitude i.e. the are VFR at 2400' under the London TMA and they "drift" up to say 2600'
For myself, I switch on to Mode C and leave it on. I have had the fortunate benefit of visiting Farnborough LARS and Thames Radar ATSUs and so have been able to see the benefit to the ATCOs and therefore other aircraft.
I like the idea of using all methods available both visual and by means of RF to enable me to see and be seen with all available information to anyone whom it concerns.
