Yes, that can certainly be true, though as so many have said there's a difference between a guy shagging around and not caring who he impregnates so long as he doesn't have to wear a condom and someone in a settled relationship who gets lied to because the woman thinks a baby will seal the deal she wants
However it's also true that this isn't the fault of the child, who still has to be supported; it's just a shame when some forget that, as well as the lying men who get rightly blasted for ignoring the needs of others to get what they want, some women do just the same
Given that we are animals and will have penetrative sex which will, sometimes, result in pregnancy, doesn’t equity mean that, as men don’t get to choose abortion, that they should be able to opt out of parenthood and financial liability, in the same way a woman can should either choose abortion or put her child up for adoption
Edited to add that the problem here is that there's no way of proving who was cheating who
Of course some scumbag men would abuse it, and of course some women will swear blind that the pregnancy really was a "mistake" knowing perfectly well it wasn't, and meanwhile tthere's an innocent child in the middle of this mess
