You may well feel so, but the substantial spread of both departure times and operators from Heathrow means that a (maybe considerable) proportion of those who appear geographically favourable to Stansted would continue to go to Heathrow.
If the daily flight left at say 1100 you would be looking at an 0900 checkin, losing any business pax who wanted to go into the office first, and likewise those high-paying business travellers who change their flight, forwards or backwards, on the day as their meetings change. Heathrow allows this.
Likewise if I am a US high-mileage traveller with miles (possibly backed up by a corporate discount agreement as well) built up mainly on United, going to Canary Wharf, a Delta flight from JFK to Stansted won't have that much appeal.
