Narrative:
Aircraft X cancelled their IFR about 10 miles from the airport approaching runway 10. Aircraft Y was waiting on runway 28 ready for departure. I told both aircraft about each other and released aircraft Y at their discretion. Aircraft Y waited until aircraft X was very close before departing. I thought aircraft Y would wait until aircraft X landed; but instead they pushed it and got close enough to aircraft X that the pilot of aircraft X called the center wondering what was going on.the pilots need to talk to each other on local frequency and should know that if they go VFR; controllers will pass along their information; but they don't separate them from other IFR aircraft in the terminal environment.
