Probably multiple reasons:
CBS reluctance to support the RCA-based NTSC color system.
In practical application, the field sequential cameras had no sensitivity advantage over the three-tube cameras.
The single-tube camera advantage of perfect registration was lost when the signal was converted to simultaneous RGB through the use of three tubes in the Chromacoder converter.
The field sequential camera was prone to primary signal leak from one color to the next due to camera tube lag. Fixing the hue shift would be difficult and complex.
Color fringing on motion (probably not awful, but noticeable in comparison to a simultaneous 3-tube camera).
Only NBC/RCA was pushing local stations to convert to color, so of course those stations bought RCA equipment - little market for the CBS Chromacoder compared to RCA equipment. RCA supplied all types of TV gear, and all the training and support anyone needed. CBS was just not a broadcast equipment supplier of the required magnitude. If anyone had contracted CBS (or a subcontractor like GE) to build the Chromacoder system, they still would have to contract with RCA and/or others to put together a complete station. RCA was a one-stop shop that the broadcaster could have confidence in.
