Anyone thinking parachuting is incompatible with other "normal" activities at an airfield should take a trip to Dunkeswell. All done on air-to-ground and with absolutely no restrictions on aircraft movements while parachutists are in the air. Absolutely gob-smacking when you first encounter it, and bizarre that it can possibly be allowed, but it is, and it obviously works because it's been going on for years.
But yes, Skydive's attempt at DTV was surely misguided in the first place - two parachute outfits within 20 miles of each other?
