There does seem to be a sizeable number of people who take any request on a webpage as a command, and comply with the email popup. Which would then generate leads.

But, this popup harassment is just going to turn away experienced users. Many of whom will be the educated, well-compensated demographic the site most wants to cultivate. And a subset of that group will have the ability to create or edit blockers, which will then be turned against the offending site. Thus making it more difficult for that company to reach the more desirable users.

That's what I would tell marketing. That wouldn't work for all companies. Some will be thrilled to get a boatload of inexperienced or naive users. But would be nice if the others would start to get worried about what they're losing with their bounce rate.
