Where did the team go?

Team changed over the years. Many were hired as contractors and they got other jobs, moved on. Most of those you listed there have left before I even joined or early when I joined the team. What they produced is on Github, their work didnt disappear because they left.

The 560% productivity claim cuts both ways

You could say that maybe, but thats just how good we got. 😉
I also did an analysis across all DHF proposals and compared output and efficiency, and then compared it to market standards to see how Magi was doing. Old Magi ran just about middle of the pack, new Magi is outpacing everything.

Altera was funded once, then rebuilt

Old Altera didnt have any functionality that could support crosschain functionality.

Critical bugs in EVM bridge code with real funds on the line are not a place where "trust the speed" is reassuring.

Its not trust the speed. Nothing goes live until thoroughly tested. The speed is us working around the clock and delivering high impact technology. Bug hunts and tests all fall under "speed" as well.
