Do we really need to use BMS RS232/USB cable?

BMS claims we have to use their RS232/USB cable for data logging or loading new firmware into your JB4.

My question...does anyone here use a cable they bought somewhere else for cheaper? And does it work without any problems.
They say you can hurt the chip in the JB4 but to me that makes doesn't make a lot of sense. Can't hurt it, would either just work or not work.
Idk :/
