We can't read all the comments that get posted here. If you see one that's worse, why not help out by flagging it, or emailing hn@ycombinator.com?
I know both Acton & Koum from Yahoo!. To describe either as "naive" or "a complete moron" is ridiculous. If that is the depth of your thought, it would explain why you're writing angry comments on a message board while they are retired billionaires.
WhatsApp's founders are awesome! But Acton shouldn't be surprised that FB behaved as they did. He is smart and knows that publicly he should act surprised.
I think it was established during the election that he isn't a billionaire. He also makes ridiculous statements on a weekly if not hourly basis, so "from time to time" is misleading.
But, as he openly acknowledges, he did sell out to a terrible company.
They could still have done a secondary and stayed independent.
That has nothing to do with nobility.
So now Snapchat's founders are noble? They did those things you mentioned and your wording is a far cry from their reputation.
As they Romans said "caveat emptor" (the buyer shall beware). Or as is is written in Faust by Goethe: "Denn, was man schwarz auf weiß besitzt, Kann man getrost nach Hause tragen." ("That one can take back home, and use, What someone’s penned in black and white." (source: https://www.poetryintranslation.com/PITBR/German/FaustIScene... ).
For these reasons I don't see Whatsapp as a Todo app. Chat apps did exist, but there wasn't really many alternatives for inter-platform chat like there is today.
Have you actually ever used it?
I do remember them turning facebook down multiple times... everyone has their price though, hard to turn down winning the lottery.
