The article isn't about the crimes against humanity though. It's about this:

Vilk is among a growing number of Israeli soldiers speaking out against the 15-month conflict and refusing to serve anymore, saying they saw or did things that crossed ethical lines. While the movement is small — some 200 soldiers signed a letter saying they’d stop fighting if the government didn’t secure a ceasefire — soldiers say it’s the tip of the iceberg and they want others to come forward.

I mean it's 200 people; nothing is gonna come out of this, hence it being a nothing burger.
