I wish the reason were more reasonable. Coca Cola is the main plastic bottle polluter on the planet, while Nestle has very questionable practices in 3rd world countries, specifically, but not exclusively when it comes to water sources. These would be much better reasons for boycotting these companies than their alleged support of Israel.

Mainly because support for Israel can be nuanced and on a spectrum as in supporting the current bombing campaign, versus the current right wing extremist government of Israel, versus the support of the apartheid in Israel, versus the right of Israel to exist as an ethno-state for Jewish people. I wonder where Coca Cola and Nestle would land... and where Turkey thinks it draws the line.
