As a business decision this seems incredibly odd. Being vegetarian or supporting vegetarianism does not seem like it would have disproportionate representation among either their target clientele or their target employees. As such it seems to me it would have minor negative effect on their perception by clients, and moderately negative impact on their perception by employees. I don't see why they would risk that for a cause entirely unconnected to their business, for which there are many less controversial ways to make an impact (energy efficiency in their buildings, commitment to purchase carbon free energy, etc).
