Narrative:

I was working sector x. Aircraft X called me for traffic advisories. Aircraft Y was descending on the arrival. TRACON has a LOA with aircraft X operations for skydiving activity in the vicinity of ZZZ. Aircraft X was in a spiraling climb to FL135; aircraft Y was descending via the STAR. ZZZ and the STAR are in close proximity (roughly 2 miles apart). I issued traffic to both aircraft when they were 5 miles apart. Aircraft X began climing northwest bound; in direct conflict with aircraft Y; both laterally and vertically. I issued a turn to aircraft X away from the traffic. Aircraft X questioned the turn on 2 different transmissions before they finally turned away from traffic on the 3rd transmission. Once the traffic was separated; I told aircraft X to resume own navigation and they informed me that they had to realign for the jump and had a question when I was able to answer. Aircraft X asked if there had been a change to our LOA with them precluding them from jumping 0.5 miles west of ZZZ. They asked me this twice because the 1st transmission was garbled. The second transmission carried a lot more sarcasm. I told aircraft X that the LOA had not been changed or altered and that 'I am not going to let two airplanes come together because of a piece of paper.' aircraft X changed to advisories and once they were on the ground; the owner personally called the tracon. The owner asked the controller in charge (controller in charge) if I was new to the facility and the controller in charge responed 'he's been here awhile'. The owner went on to say the operation was ridiculous several times and that I needed to be 'tuned-up'. I'm not sure what the owner meant personally by 'tuned-up'; but where I am from that means assaulted physically. We have had many issues with this company in the past. The general consensus is that this company thinks they own the airspace because the have an LOA. One of this companies slogans [implies jumping around jets]; a practice that they seem to take serious enough to get close to other airplanes. I recommend that this company either move to an airport away from the main arrival route or get used to turning for traffic. It's utterly ridiculous that an aircraft operator or pilot for that matter is so upset about turning for conflicting traffic.

Title: Controller reports of a VFR pilot who didn't initially turn as instructed away from another aircraft that was IFR. Pilot took turn and then questioned Controller as to why they had to turn. Controller advised it was for traffic. Pilot questioned if something had changed to the LOA. Controller advised no; they were turned for traffic. Company owner called TRACON and wanted the Controller 'tuned up.'
