Well, they took WireGuard, wrote a Rust implementation of it, refused to collaborate with Jason, who's been trying to get a Rust implementation of his protocol off the ground, then rolled it out as a proprietary offering that WireGuard itself is not allowed to connect to. This seems like the sort of analysis that would be pretty cut-and-dried among open source advocates (I'm not one of those, so I'm not saying it's cut-and-dried for me).
Your previous rooting interest in this story would have been for Rust itself. And Rust itself would have been been best served by having it host the dominant sanctioned userland implementation of WireGuard, not merely as an implementation detail for a commercial offering that also treats WireGuard as yet another implementation detail. Rust? Important! WireGuard? Important! Warp? Who gives a fuck?
So this is a bit of a surprising response to see from you.
Apologies for the late edit:
I should lay my own cards on the table here.
First, it's not much of a secret that I'm no fan of big Flare. But just to be clear: good friends of mine have worked there, and several other people I deeply respect have as well, and I don't judge any of them for that.
Much more importantly: Jason Donenfeld is, to my mind, the hardest working person in show business, and he's set himself on one of the most important projects in network security, basically all on his own, and the momentum he's managed to achieve doing that is insane and a little inspiring --- especially given the amount of shade he's been repaid with by network security luminaries --- and basically the last thing in the world he needs is to burn cycles worrying what some giant corporation is doing with his work (which, sure, does not include this Rust implementation, but very obviously does include all the hard protocol design and validation work he's been doing over the last several years, which, if it were easy and straightforward to do, several people would have done before him).
I've done about as much serious technical work on WireGuard as you have --- to wit: none, though I am a loyal, diligent distributor of WireGuard stickers. My partners all feel the same way, so we've just been sending the project cash.
If your employer has done the same, and dumped a giant bucket of cash on Jason in exchange for having gotten so much mileage out of his work, that would be an excellent rejoinder to this particular set of concerns.
Eagerly, therefore, awaiting my comeuppance on this thread! :)
