Tangential from your point, but I don’t think this is a submarine article. This is just a single blogger. “Submarine article” typically refers to articles written by large news corporations (NYTimes eg) and incentivized by PR firms - none of which applies here.

The reason I mention this is that “submarine article” is typically used to cast suspicion at the aims of the article. I can’t see any reason to do that to this article.

I was suggesting OP may have been influenced by submarine articles since the popularity of speed dating is a potentially unfounded premise of their argument. (Personally, I know very few folks who’ve done speed dating but of course that’s anecdotal.)
