Personally (and with a club hat almost on) I've no problem with the use of GPS. It's a tool, nothing more. It shouldn't be a substitute for knowing where you are and if the proverbial hits the fan being able to get yourself and the rest of the party off the hill in a safe manner. Not everyone has the benefit of many years' walking and running in the Lakes to build up a bank of personal knowledge.

At least with a GPS it is within the party and doesn't affect others whereas large support parties increase erosion on the route and have knock on effects for those that follow.
