I have direct personal experience of Hong Kong's points-based scheme, the Quality Migrant Admission Scheme - which, it should be noted, is a very niche scheme, largely unknown even amongst expats. The vast majority of skilled immigration comes on a simple sponsored work visa...
QMAS gives you a few extra points (5) if you are applying alongside a degree-level-educated spouse, and a few more if you're bringing children (5 or 10 for 1 or 2 children). Given that the 'pass mark' is 80 - which doesn't guarantee a visa, just allows you to apply - it's neither a trivial amount nor a particularly significant one.
The article is absolutely wrong. It states Canadian immigration scores you out of 67 points, that system has been phased out in 2017, before this article was written.
Also, Canada absolutely gives weightage to your spouse's age, English/French skills, education etc. up to 40 points.
The Express Entry system introduced in 2015 (not 2017) is just a change to who can apply to the system indicated above and the other systems integrated with Express Entry, rather than being first come first served. It doesn't determine approval. (Though for the provincial nomination programs, some of the other hard parts happen before Express Entry, not after.)
Express Entry amalgamated FSW/T and CEC streams and digitized the process, for which you used to have to send paper applications before. The Quartz link made 67 points the centrepoint of the article, which that is the first step, you still have to enter yourself into Express Entry pool, where spousal points are calculated separately and in fact does impact your final points tally.
