Intel is chopped up into tens of millions of tiny slices, and everyone with any form of retirement savings has a handful through some sort of fund.

Generally these people barely know they're shareholders, they receive none of the paperwork needed to vote at the AGM, they have a slice several orders of magnitude too small to exert any influence, and they have no way of identifying or contacting other shareholders to take any sort of coordinated action.

Anyone who expects X to be done by shareholders is going to be disappointed.
