Yes, out of the gate Citizens Band has a few Public Relations strikes against it.
First, it's essentially unregulated, and some people with interest or knowledge of CB have probably heard or heard about the rude weird talking people that hang out there with their high powered amplifiers ready to stomp on you.
Second, it's not as exciting for people as the Internet with audio and video with much larger audiences.
Third, it can seem seriously outdated to people used to full-duplex cell phones and video chats.
Fourth, in a world where everything is smaller, some people might not want to deal with larger antennas.
Fifth, there is FRS. Some people prefer to stick to one frequency and use CTCSS relishing in the static free environment of FM when squelch does break.
