Mr. Glass seems to expound the other extreme. Some have called him a basher. I don't know if that's the major concern as much as his negativity.
It's good to have a counter perspective, especially if it's well thought out, logical and well supported but pure unbounded negativity just for the sake of it is unfounded and undesirable. I, for one, don't like it and would support less of it. It's hard to ask a tiger to change its stripes so I vote to ask him to depart.
