This is disgusting. Remember that this letter is:
1. for common shareholders who will get absolutely nothing out of this deal.
2. yet it's asking them to sign so that they can go ahead with the deal.
3. And to top it off, "I'm reaching out to share some great news"? Are you kidding me?
To be clear, I support all entrepreneurs regardless of what ridiculous business model they're trying to pull off. I even think Magic Leap should be given a benefit of the doubt and they may be able to pull it off.
Also I think it's great that silicon valley celebrates failure. Without this type of environment it's hard for founders to shoot for the stars.
That said, people have taken this too far, and it's become ridiculous. It's no longer about it being ok to fail, but it's about "I failed, so what? I'm the genius and I totally deserve it and you just paid to tag along."
I totally despise bullshit like this. If you lost, just say you lost. And say sorry. Don't bullshit people about how "it's a great news that I'm asking you to sign this letter so that other people--not you--will get the money you actually deserve".
