I understand why you are worked up. They are probably trying to come up with ways to handle outland applications. Inland applications are less complicated and don't need verification services outside Canada for the most part. IRCC probably relies on third-party services to do background checks in countries like China, India, Nigeria, and so on. With COVID-19, these services are affected, so this is likely temporary.
Also, CEC candidates are able to score above 470 easily, so by removing them from the pool, the score could drastically drop if they choose to do an FSW draw when things get better. Personally speaking, achieving anything over 440 is extremely hard for FSW candidates while anything over 470 starts to get hard for CEC candidates. So, doing separate draws for these categories makes the playing ground level.
