Hey Pitlord,
It's not unethical at all. Doing a normal draw would've been unethical since many people's profile was not updated because of the bug they have...
This draw is a PNP specific draw, the provinces have guidelines and rules on who to nominate to fit their needs. Maybe the individual with 186 points is more suited for what the province wants vs. what an educated individual with 469 points could offer. Farmers are in high demand throughout Canada, but people with PhDs in theater are not.
If the government is sloppy, slow, unprofessional, corrupted and that bothers you that much perhaps you can find another country to immigrate to. I mean that in the sincerest way possible, as in I can see that a lot more things will bother you if you live here permanently.
