Correct. Here is a longer explanation that I was getting ready to post before seeing your comment.

I suspect Cathy2's explanation is correct.
Finish Glass Magic is composed mostly of sodium triphosphate, with several other minor ingredients. Illinois and many other states
banned high-phosphate dishwasher detergents about a year ago. I'm not sure, but probably dishwasher additives are also included. Reportedly dishwasher detergent accounted for about
10% of phosphorous in municipal wastewater.

You can certainly try baking soda and borax (sodium borate), although neither is present in Glass Magic. It won't cost you much to find out if it works. Keep in mind borate may be slightly toxic when ingested (I doubt there would be much residue left on your dishes) so be a little careful using it in the kitchen. I wonder what the sodium bicarbonate is there for. I suspect most of the cleaning muscle is provided by the borax.
You can buy sodium triphosphate of various purities. I don't know what grade you'd want for a dishwasher additive. Also I'm not sure how important the minor ingredients in Glass Magic are. But I'd guess sodium triphosphate would work almost as well as Glass Magic. And it would be even more effective at ecological damage!

Chlorine bleach can be tough on certain metals and plastics so they'll probably tell you not to use it (I'd guess very occasional use wouldn't be much of a problem). Glass Magic contains a minor proportion of sodium dichloroisocyanurate, an antimicrobial. You probably want anti-scaling agents as well as disinfectants to clean the innards of your dishwasher so something along the lines of Glass Magic might be ideal. There may well be products specifically formulated for cleaning dishwashers (you'd kind of think they'd clean themselves, no?).
