Understand that the Zoners are a diverse people, coming from all over Sirius and all different situations. Many Zoners, like the council chairman, prefer fresh, traditional food. Some Zoners prefer a cheap alternative, not caring about the food itself. Ultimately it comes down to the choice of the individual. If you have a problem with synth food, perhaps you would be best served by a clever marketing campaign against it, or for alternatives, rather than this suspiciously-timed lashing out. We are at the end of the day, consumers, not competition.
To be completely fair, synth paste is present on more freeports than has been said here- but that does not mean it is the staple of those freeports. I personally have found an affection for rice noodles...
As ever, it is difficult to get the "full picture" with the Zoners. Don't paint with too broad a brush.
