They have actually said it though. Granted this was during Mendicino's disastrous time as immigration minister. They wanted to "give low skill candidates a fighting chance". The problem, like I mentioned in a followup comment, is that low CRS is not the same as low skill. Low skill generally refers to people working jobs with a low barrier to entry. This is great. Give them an honest shot at PR, and I will support this at the cost of my own candidacy.
On the other hand, low CRS is just dumbasses who got a worthless PG diploma in Canada while being unable to string together one coherent sentence in english. This is the group I have issue with.
MM said they wanted to give "hard working candidates with lower scores" a shot at PR, and there was a calculated effort to focus on low scoring candidates. We can use the excuse of the pandemic, exceptional circumstances or whatever else, but this selective drop in CRS for some candidates and not others was a very calculated move. Even in the two lawyers association letters to the new immigration minister, they talk about some importance that these low CRS candidates apparently have. My understanding of it is that they're confusing low CRS with "low skill". Low skill are essential. Low CRS are scum.
