IMHO these were designed to hit a price point ... for telephone connections. It is far from my favorite connector. I am surprised we don't have more trouble with them, as if it isn't enough.
They undoubtedly
were designed to meet a price point--at pre-breakup AT&T. As such, long-term maintenance costs were part of the "price point."
RJ connectors were designed to
work, and to keep on working, decade after decade, without an expensive visit from a truck with a "Bell" logo on the side.
