If i remember BA didn't quite pull out. If i remember correctly at the time BA had Gatwick slots and Aurigny flew to Amsterdam. A deal was done to swap slots between the 2. Even back then Flybe / British European / JEA what ever they were then were flying GCI - LGW. What we also have to remember is Gatwick is under new mangerment and it wont be long before they squeeze the smaller airlines out like Aurigny. As you quite rightly say Easyjet / BA may not be interested on GCI-LGW on its own but what about a triangular route with Jersey to increase the load factors. Soon airports are only going to want bigger aircraft earning them more money - its sad to say but small regional airlines have had their time. I cant see Aurigny / BI ever running 737's / A319's just to keep gatwick slots. Guernsey need bigger aircraft from bigger airlines which can fit Guernsey into their flight network.
