I agree with you. The article also attempts to minimize the importance of the issue, saying "stop panicking [...] it’s not the problem you think it is".

Let's assume that their figure of 1% is correct. In the UK in 2021 alone there were 694,685 live births according to Google. That means in one year alone nearly 7,000 children were from "EPP". That's an enormous number of people, mostly men, potentially wrongly pursued for child support, or battling through the courts to be given access to a child that's not theirs, etc.

That strikes me as a hugely important issue.
