Why isn't this Vegan??

There are a few things that could so easily be egg and dairy-free. But they're not. This grinds my gears. If I had the time, I'd write to all these companies suggesting animal-free alternative ingredients, but as it stands I'll probably do Cauldron and Co-Op (because they're wonderfully ethical companies who might actually listen) and then just stop there.

• Cauldron sundried tomato pate (not sure about the other flavours)
• Co-op swiss-style muesli (and most other mueslis, surprisingly enough. For some reason, they contain milk powder)
• Wine (all co-op wines are veggie and vegan. Pretty much all other mainstream wines are fined using Isinglass, made from fish.)
• Quorn products, and other meat alternative products (why would you alienate half of your target audience by throwing egg into the mix??)
• McDonalds Veggie Burger (I can understand why this isn't vegan, but for the love of god, why isn't it vegetarian?!? Yeah, it's fucked up right.)

In wonderful news of the opposite kind - it seems that Birds custard powder IS Vegan - yay! :)
