Looks like "anti-airbus" or "pro-boeing" article written on purpose:
Sabena - since owned by the SAir Group, a decision pro airbus is the more logical thing(IMHO). And the overblown order is rather to be attributed to Philipp Brugisser's megalomaniac concepts.
In the other cases, it is all about state-owned carriesrs and with exception of AC
, some lands which have a different culture(it might be tempting to say "third-world lands", but it is not entirely correct. A decision to buy either Airbus or Boeing might be in this cause not entirely driven by economics, but also by political reasons or even by the voice of some mighty man having all the power and reigning single-handedly. As far the actual, factually-backed accusations in the article go, it appeared to me that these are to a significant extent based on coincidences and assumptions. And, when it comes to the Air India, KAC
and the Syrian deals, I would speculate, political reasons were(and still are) much stronger to go with Airbus than Boeing, especially in the present time.
A bit of politics might have played also a role in the Air Canada deal(pro-french decision), but I wouldn't speculate further on that, it is just my guess.
All-in-all, for me, the article looks largely biased. And, last but not least, I think Boeing has an equal share of deals conducted that way(if not a larger share than Airbus)
