When I created this thread, it was before Trump revoked Biden's Humanitarian Parole. If you read my first message the issue for me was that Trump had directed USCIS to "indefinitely hold" and not process applications legal lawful applications from people who arrived via CHNV. This is in fact not legal for the agency and Trump to just never process applications that are consistent with US law. The Cubans that I sponsored paid for their i-765 work authorizations ($460), paid for their i-693 medicals ($250), paid for their residency applications ($1,440), paid for their i-765 renewals based on pending residency ($260) and it isn't right for USCIS to no longer process their applications which are based on US immigration law (specifically the Cuban Adjustment Act of 1966).
Since then Trump abused the use of the Alien Enemy's act of 1798 by sending 238 unknown people to a prison in El Salvador. He is also threatening to send US citizens to this same prison without the right to a trial.
He is prematurely ending the parole program that Biden afforded these people which is well within his rights, however it's a pretty crappy move. (I'd had like to use other adjectives to describe that move, however it's not allowed on this site). I know several people who are making arrangements to fly home. These were lawful immigrants that were following the laws of society, working full time, paying taxes, and contributing to commerce. It's not a nice thing to do to innocent people if you ask me.
I cut the part of your post talking about abuse in the program because it's distracting from the main point of why I am upset which is the first paragraph of this post. My unbiased views of this program is that USCIS handled it poorly from the very start just like every other immigration path they screw up badly. People were poorly vetted, people were processed in random orders, the more people you sponsored the more likely you were to get your entire group approved.... I heard stories of people paying for sponsorship and it was just an entire mess to be honest. But I will say since I am plugged into many many communities that the vast majority of people that came through the program are good lawful people that were following the rules. Ask yourself this... Why is trump turning his attention to these 550k people who went through a legal lawful process that biden allowed verses the 5 million illegal border crossings that happened at the same time? Answer - it's much easier to go after honest people who follow the rules... much harder to catch the ones that did so illegally.
