Mainlander literally killed himself, so he obviously found the idea depressing. It's depressing in the context of Judeo-Christian, forward-thinking, progressive culture. We like to think our future will be better than our past. Otherwise, what's the point in trying to overcome obstacles?

Mainlander's point, as I understand it from second-hand sources, was that the only one who was perfectly positioned to judge whether life is worth living was God and he gave a big thumbs down. That means every trace of human optimism is foolish, every hope and ideal wrongheaded, every grim attempt to carry on despite the odds is laced with tragedy. If we're living in God's carcass, how are we better than ants buzzing around a rotting animal? Ongoing life would be grotesque.

That's not to say that I'm depressed like Mainlander. My philosophy draws from various sources.

I've written about Mainlander's view years ago on my blog, in 2012 (link below). The idea is also featured in my novel, "God Decays." I also just wrote another article on this pessimistic scenario, called "Empathizing With the Plight of Being God," which will appear on Medium within a week or two.

Pagans may not have been depressed by the idea because they viewed time as cyclical, like Roger Penrose. You'd have to take up the evidence of cyclical big bangs with him. It's mostly theoretical rather than evidence-based, but that's the current state of theoretical physics. Evidence is hard to come by in that field because they're asking far-out questions.
