My guess is that they made them incompatible to avoid customer service issues due to the differences in supported refresh rates. Bit Cauldron may have also changed the frequencies their system operates on to avoid interference from everything else on the 2.4 gHz band.
I'm not seeing that. According to the specs I found for the ZF2100 they also support 144hz.. See below..
