Though public figures like Nachum Barnea in Yediot Acharonot have written explicitly about the disgusting actions employed by Eidah Chareidit "activists", I have heard even more disgusting examples of Eidah Chareidit "activists" promoting violence and intimidation against other Jews (including Chareidi Jews) from Chareidi Jews themselves. Therefore, let no one be confused by any "smoke screen" the Eidah Chareidit or its supporters may attempt to create; the boycott of the Eidah Chareidit is a result of the Eidah Chareidit's actions which promote Sinat Chinam among Jews, and is, therefore, a very positive step which will support Ahavat Yisrael and true Achdut.
While I dislike the Eidah Chareidit's anti-Zionism, I would not encourage a boycott of products with their Hechsher simply because of their offensive philosophy; but since they sustain this philosophy (as well as many other things on their agenda) through the actions of their "extremists" who promote the utilization of violence and intimidation against those who oppose them, we can all be certain that the Torah requires us to do what we can to stop this utilization of violence and intimidation, supposedly for "Torah purposes", which is actually simply creating an enormous Chillul HaShem!
All supporters of Ahavat Yisrael and Achdut within our people can only hope that more and more Nestle products will be produced without the Eidah Chareidit Hechsher until all Nestle products will be free of that Hechsher, and that other manufacturers will follow suit, and that most or all will choose to replace the Eidah Chareidit Hechsher on their products with other Hechshers.
As is well known among those who follow Kashrut supervision, the Eidah Chareidit Hechsher, as good as their Kashrut supervision is, is not the best Hechsher as far as Kashrut supervision goes; and it is certainly not the best Hechsher as far as the Ruchniut (spirituality) of the supervisors goes.
There are many Mehadrin Hechshers other than the Eidah Chareidit Hechsher, and at least a few of them are known as having a higher level of Kashrut than the Eidah Chareidit Hechsher. I certainly advise all manufacturers who want a Mehadrin Hechsher to find one which is not Eidah Chareidit.
The website (in Hebrew) of the boycott against the Eidah Chareidit Hechsher is:
