its really simple and not that contentious: Primal connects to their own "caching" server that does some mysterious filtering/hiding, image-swapping and mysterious post-ordering (promotion of content), rather than reading directly from relays. yes, you CAN supply your own caching server, if you happen to run one or know someone who does. but you CANNOT (yet) simply instruct Primal not to do this and read directly from relays.

Odell has explained as much, though he makes it sound less nefarious than I am here (which tells you how each of us feel about this "feature"). whether you see this as a good or bad thing is a matter of subjective taste, but the facts are the facts.

there is no argument, just preferences.
