Sign this - this is a perfect example of how regulation is being used to give advantage to large corporate institutions who can easily obtain legal permissions for things, the government has been lobbied by some PR dept to introduce this because it benefits them somehow and because there is no one with the budget to lobby against it, it gets passed. There are thousands of regulations in existance now that have a similar effect on each and every industry, its a proper racket ands it will only be overturned if people point it out and expose it for what it is.
