I think perhaps you misunderstand. Most people don't think parents bring their kids along to deliberately disrupt travel. At least, I certainly hope that's not what people think.

But, intent is irrelevant. It doesn't stop it being annoying for some/many people.

As for the picture here. I suspect the reason more people are looking this way than usual. It looks to be a business class cabin. I know many people book business class because it more likely puts you at some distance from the noisier cabins. This looks like they probably have a dedicated business class boarding door. So they likely realise they're coming to sit in the same cabin.

If you book in economy, you're used to and expect it more, I think.

here's a solution:

don't take planes for a few years until the child doesn't cry for no reason anymore

just stay home then

you chose to have children, in this day and age where all they’ll ever know is suffering and pain

so don’t make everyone else’s life worse because you just had to creampie someone.
