Both Linux and MacOS followed the Unix implementation, both of them are derivatives of Unix, so why would that change? Unix derived from Multics which chose LF.

The issue is that none of the print carriage movement ASCII characters should be used internally to indicate "end of line", because each of the chosen possibilities are used separately to indicate different carriage movements.

The logical decision would have been to choose one of the "separator" characters to indicate "separation of one line from another" and then allow the I/O drivers to decide what to send/receive to/from a particular device.
