IMO, it's because Evan Spiegel and Snap by extension is just as cutthroat and unlikable as Mark Zuckerburg and based on what I've read about it I feel like he would be doing the exact same things as FB is if the roles we reversed.

This doesn't feel like some altruistic, whistle-blowing gesture for the good of the consumer. This feels like Snap being pissy that there is a bigger bully on the playground.

I'm not saying what Facebook is doing is okay, because it's not, but Snap has a vested interest in FBs demise and Spiegel and Zuckerburg have their own pissing match. I have a hard time feeling sympathy for either company in this issue.
