Plessy moves to a licensing model

Interesting move by Plessey.  I wonder if there are underlying reasons why they couldn’t get interest in actual manufacturing – is it that the UK financial ecosystem is biased against deviation from the design-it-at-home-but-make-it-all-in-China model that was (but no longer is?) popular for the past 20 years?  or is something else going on? If the former, then things wouldn’t seem to bode very well for the various Brexiteers’ economic promises if innovative UK companies can’t get funding to manufacture in the UK
