I don't think that there are political reasons...only if Genetec's owner want to become Canadian president :)
And, of course, not technical, because Hik is not worse than any other in this regard.
It is definitely marketing/sales reasons. Genetec is still commercial company and operate to get more market share and profit.
I assume one main reason: Genetec's SIs are mostly selling higher brand's cameras and suffer from Hik cameras sales. They sell Genetec, but big money comes from cameras. Hik's margin is very low in compare with higher brands, so they want to compensate this lost from software license price.
Simple!
But this is very big strategical mistake.
Huge cameras projects are not high price brand's projects anymore. Huge cameras projects become possible because of low price of cameras, so Genetec is going to loose them.
Interesting to see when they step back and return Hik in list. I predict very soon :)
