BBC and CBC are already public agencies, as the author suggested as a solution. arguably, given who pays them, the party of the official opposition should appoint the heads of them both.
imo non-partisanship was the artifact of another time. in another life i wrote occasionally for establishment media and met many players, and i don't bother with any mainstream news anymore. these days i prefer to read the writing on the wall.
That doesn't seem like a solid strategy - for example, here in Australia the current opposition are the ones who did appoint the heads of our national broadcaster (when in Government) and were widely condemned for the political nature of the appointments (actually bypassing an independent selection board to make ideologically motivated appointments) and also for their political interference (or attempts at it) both while in Government and while in opposition (as they are currently).
Their attempts at political manipulation is arguably even stronger while in opposition, so if anything they would be even more likely to make politically and ideologically motivated appointments!
my argument is that media is the only real loyal opposition, and so being appointed for the term would have them do their actual job instead of the influence peddling they're reduced to now.
