Well, from what I've read the book and the products came substantially after he started voicing his concerns, which sort of implies that he might've taken the matter in his own hands since no one would listen to him.
Even assuming he is a complete loon, the theory of an environmental cause is actually quite plausible. Perhaps not fungus, not phosphorus, but something in the bedding that just knocks those kids out.
With regards him being evil - I don't really see it that way. Why do you say that parents stop following established best practices once they wrap their kid's mattress? Parents aren't idiots, are they? What he's advocating for is orthogonal to existing prevention measures, both easily combined.
The very many parents who believed Wakefield and didn't immunise their children prove you wrong. Some parents are scared, and want to do the best, and cannot assess risk, and cannot understand scientific research, and thus are vulnerable to woo.

I have no problem with someone saying "Cot death could be caused by environmental factors. Let's do lots of good quality research to see if we can discover that cause."
Sprott did not do that. Sprott said 'I have found the cause. This is the cause. There is no room for doubt. By not following my advice you are killing babies. By arguing against my advice you are covering up mistakes that you've made, or you are corrupt'.
Sprott says that no babies have died on wrapped mattresses. This is false. Babies have died on wrapped mattresses.
Sprott claims that toxic gases are produced by fungus and the fire-retardant chemicals. This is false - it's not possible to generate those toxic gases unless you do weird things in a lab. (ie, it doesn't happen in the home when the mattress is used normally.)
So what he has done is diverted attention from correct information; made it harder for parents to remember and follow correct information; caused fear and uncertainty among scared people. He has ignored the very clear recommendations against his advice. And finally he's making money off this FUD; he's using the conspiracy theory as a marketing gimmick.
Yes (speaking as a parent), parents are idiots. We're expected to raise children without a real guide except our own life experience, flawed as that is. We are continually bombarded with media that expects parenting to look one way, while reality is far different. The scientific method doesn't work for parents; we generally try ad hoc procedures that reinforce our confirmation biases.
Yes, parents are idiots. It's a testament to the resiliency of children that any make it to puberty.
