The people playing music and jamming, people that think they own a frequency and the guy that keys up randomly to say "you like sucking co**" all come to mind.
I dont get that either. I think the mentality that everything has to be peaked and tuned or modified keeps most cbers from buying good equipment. They've been told for years that cb shop magic makes them talk further and they want to believe it. The modern hf rigs do a pretty good job on AM where many of the older ones had such narrow bandwidth that a cheap cb sounded better. I can't think of any good reason to buy an export radio for a base in 2018.
I have a good friend thats a about 30 years older than me. Hes been on 11 meters most of his life and wanted to build the best cb station he could for his retirement years. I gave him some suggestions for radios and amplifiers but he said they were too expensive. Over the next year he spent even more money buying old junk equipment that looked cool.
