A twisty maze of regulations and restrictions -- in the US, in Mexico, and in other countries -- make it very difficult for anyone to exercise the right to request asylum in the US, even to follow the long and slow procedure the US imposes for doing so.

The "Title 42" system of making asylum-requester stay in Mexico runs into a problem since Mexico won't let them stay there.

An additional aspect of oppression in this system is the US requirement to use a snoop-phone app, "CBP One". Those programs are nonfree and typically malware. So are the operating systems of the snoop-phones themselves.

For governments to make them the only way to communicate with a government agency for some purpose is in itself unjust. So, for the same reason, are "web apps" that send substantial Javascript programs that users have to run in their own computers. Knowing the US government, I expect it abuses that power grossly when it gets the chance.

I'm sure most of the people compelled to run "CBP One" hardly care about that injustice, given the painfulness of their situations in general. But unlike those. this one tends to spread to non-refugees -- to everyone.
