I don't like them and I ignore the person that is running them. We have the "kids" channel (sadly, it's channel 19.. I feel bad for the truckers that have to deal with them) and they all have 2-3 different roger beep modules all installed in their radios with their "endless echo" nonsense. Fortunately, the local SSB community won't deal with echo and roger beeps.
It would be awesome if we could convince the kiddies to turn all of it off once in a while and run some SSB, but oh well... wishful thinking, I guess.
