They have teams of lawyers so suing them does no good.
EDIT: I assumed this was a partnership. I have no clue if they partnered here. Just speaking broadly after watching a couple of my founder friends get screwed by Amazon.
Maybe it doesn't count as partner, maybe it does.
So it seems odd to call out AWS that they should have partnered with soracom or they aren't being ethical.
$187M for an exit is not that large. Were they offering a price in that range to AWS?
It feels a bit like some of the AWS IoT offerings are throw stuff at wall style.
I'm not THAT blown away by AWS offerings, they feel like copies of a couple of players offerings and at least when I last looked not THAT polished up. That said, plenty of folks will use AWS because they are already there. But it does feel like space for other still here maybe.
I mean, it sounds like they / their investors were shopping and the KDDI offer of what was reported [1] to be $180 million won? Who's to say if AWS participated in that or not (I, speaking only for myself, have no knowledge on this). I don't understand at all why you think that this is anything unusual or nefarious, and it seems like the founders got a good exit regardless?
