Airports like LHR or LGW have good outbound catchment areas. LCY less so. As other posters have said, LCY is very convenient for people coming to the City and indeed also the West End. Lots of people work in the LCY catchment. Rather fewer potential travellers actually live in that catchment. So the dominant flow is passengers inbound to LCY in the morning and out again in the evening. By and large, it requires quite a bit of yield sacrifice for airlines to fill their morning departures from LCY. If you are travelling on business to the City, flying into LCY saves you time and you (or your company) is prepared to pay for it. If you are travelling to (for example) Paris for a meeting, the chances are that you can get there faster either through another London airport closer to your home, or on the train.
CDG is not a particularly convenient airport for downtown Paris compared with Orly, and CityJet has been trimming back its (once fabulously lucrative - until HS1 opened) Orly service in recent years. A CDG route would therefore rely on connecting traffic, and it's unclear what advantage LCY really brings for that compared with other London airports.
I don't think you will ever see an LCY-CDG service again. That's nothing to do with CityJet, just the nature of the traffic and the competition.
IMHO, Air France would be better advised to negotiate with Eurostar for direct trains St Pancras-CDG (and onward, perhaps to Lyon or Nice) which could carry an AF code.
