Frank, The subsidy was a cruel myth, propogated by individuals for their own aggrandisment and has done incalculable damage to the real debate which is 'Why does day VFR need ADSB ???' and why should owners of C 172 that never see controlled airspace need anything more than a serviceable VHF to go into CTAF.
The separation myth is another cruel impost on the day VFR community, most of whom are smart enough to stay away from CTAF when RPT may be active.
