Completely agree with this. I think there is an analytics blindspot underpinning it. We don't measure the amount of people inclined to just close the tab when they see this, or the negative sentiment it incurs. We might see a nominal rise in email addresses from bots and other braindead folks who fill in these forms, but the negative effect isn't measured.

I wonder if the time delay on these pop-ups is set to avoid being measured by the "bounce rate" or "0-10 second session duration" analytics tools.

This would be especially interesting to measure. While the 0-10 second bounce rate on any site will be somewhat high due to people just looking for something other than the page you give them (I see 50% bounces on a small business site with zero ads), and it's difficult to distinguish these from people who didn't like the ads or format, you could get a precise measurement of exactly how many people close the page within 3 seconds of the pop-up appearing.
