One notable instance occurred around a regional airport without Class D.
Flying 10 miles out in Class G airspace I was transponding and talking to the radar controller. An infamous airline arriving and positioning for landing had detected me on their TCAS and started bullying the controller to instruct me to move further out. There were implicit threats made by the pilot that he would file an airprox if I didn't.
Fortunately the particular ATCO shut him up and I carried on safely on my way.
There are definite signs that certain airlines are pressurising ATCOs to cut the corners, to lean on non-commercial traffic, and to get operators to ask for larger than necessary airspace reserved for them
We are at the start of a proposal to gain Class D for a local regional airport. Again, they are asking for a huge area of airspace to be reserved for them, and squeezing both laterally and vertically the available airspace for GA users.
