The seasonal battle over kitniyot has already commenced. According to Ynet (http://www.ynet.co.il/articles/0,7340,L-3686451,00.html), Rav Ovadia Yosef takes a machmir--though not entirely accurate approach--that the Ashkenazi custom of refraining from kitniyot has been around for 600 years.
As Rav Bar-Hayim pointed out, we are in Eretz Yisrael, not Europe, and we should all be adhering to the local custom. The error of importing this foolish custom only occured 100-150 years ago and has become increasingly popular as it became more profitable for askanim (wheeler-dealers).
And speaking of Europe, a number of years ago, Rav Shaul Yisraeli of the Merkaz HaRav Yeshiva recounted to Rav Bar-Hayim how peanuts were served during Chol HaMoed in Lithuania since they were considered a luxury.
Maybe we could argue whether peanuts are really kitniyot... or whether they shouldn't be included on the Ever-Growing List of Kitniyot and Things That Make Askanim Rich.
It is interesting why Rav Ovadia Yosef couldn't just take the easy way out and admit it's a foolish Ashkenazi custom and the Sefaradim have been correct all along. IMHO, this would open him up to admitting that we're in Eretz Yisrael and that we need to worry about the "big things, not the little things", like korban pesach, the Temple, etc. etc.
By creating a big deal out of a little deal, we can continue the Purim veil over existence right through Pesah.
What is especially nice about this article is that Ynet has appropriately given credit to Rav Bar-Hayim and Machon Shilo for its revolutionary halachic ruling.
We are looking forward to an official reply from Machon Shilo.
