I agree, My previous work environments have all used vita-soy or soy-good. Both contain added vegetable oils, flavours and water added My current work uses bon-soy which is just soy milk, nothing added, and so reacts to the steam wand just as easily as regular milk. My only notable difference is that a little air goes a long way, but still just as silky smooth as regualr milk. Vita-soy (etc.) is a joke. It's more like soy flavoured-milk. To make the equivilant regualar milk you'd have to get 200mls water, 100mls milk, add a good slushing of vegetable oil, milk flavouring (to compensate for all the water added) and a touch of sugar (check the ingredients of vita-soy!). Now you try getting micro-foam out of that!!
