Rac Yoni Rosensweig quoting Rav Yoel Ben Nun on kinyiot.
Summary: The primary reason for the gezira is to prevent people from mistakenly eating chametz. Finding chametz in the kitniyot is a secondary reason only. Therefore the irony of today's world in which the market is flooded with chametz substitutes is tremendous. The rabbinate actually had to put out a warning about certain wafflim (wafers) that were chameitz but were put in KLP packaging.
The upshot of this mistaken approach is:
*kitniyot products (eg oils) should be kosher
* no one should touch the substitutes
I would add that the need for the chameitz substitutes adds fuel to the anti-kitnyiot fire (See? even you people can't go a week based on a real KLP diet).
