I have experienced what Marc described, but I learned to avoid them so it has no impact on me. If they are becoming less common it's mostly because the old farts are dying out. Adding to what Marc described, a lot of HAMs want to only have meaningless social chat, which is not what I got radios for. I deleted all the nearby repeaters from my channels because I'm fed up with these people. I asked about joining a club in my hometown and was told no, to start my own. After I moved I went to the nearest club meeting and was mocked for only doing 2m (and 440). I've asked about starting nets twice and was turned down. Gave up on ARES when they made training and deployment as criteria. Skywarn was moved to a repeater I won't use because of policy. Really nothing left for me on HAM. GMRS turned out to be disappointing as well, but I monitor it more now than HAM.
Back on topic, there is a new GMRS repeater only up 30ft but the owner wants to link to a node (did he miss all the brouhaha?). Same frequency used by other repeaters that likely overlap his area. From what I recall the linked system owner shut down so I don't know why this is even still available.
