Apologies to the list.

You're still presuming ill-will. I'm seriously offended. I'm not upset
with the glib talk, I'm upset that you think I have ill will.

We specifically told you guys privately and publicly when asked that it
was simply to be able to do it in 2 weeks. Check out the code, it was
much faster to do it that way. The spec wasn't complete and I have
personal biases against doing it on the main-chain since it would
benefit things if there was smart contract proections on the main chain
as well, which I figured would be more controversial. I never said
anything about public commitments to transactions. In fact, I'm pretty
good at figuring things out and tend to cargo-cult things (since culture
is the genetic memory is civlizations), if I saw BIP141/SegWit required
a commitment instead of it being optional, I would've probably thought
about it. Why wasn't this required as part of SegWit? BIP141 is still
vulnerable. Why did you pull this out just now? I'm totally blindsided
here, hence my earlier reply of wanting to resolve it in the Extension
Block proposal.

I never participated in that, and the specific announcement here
indicates that changes will be happening. The intention was to get it
out as a draft and *working* demo code.

That was specifically after Core developers accused me of publicly
acting in poor form without any understanding of the situation. I was
especially annoyed because all of you are acting with similar secrecy,
even worse, there is specific organization by Core which the public is
not aware of. Think about it from my perspective, you all blocked me out
intentionally for months and then accuse me of going to journalists for
a couple hours before? I'm seriously hurt.

Nice you cut out the beginning which explains on *why* I didn't reply:

"with an embargoed press release in Forbes.

That's how you roll now, right? :-/"

Why didn't you include your entire message?

That was in reply to my initial message reaching out to you and Adam
Back:
"Hi, would you like a phone call tomorrow?

I am in Thailand right now, I understand if what I did is upsetting, my
goal was not to upset you.

I deeply respect you both technically, but I do believe what I am doing
is right. If you could find a way, I would be extremely grateful if we
could chat sometime."

Replying with a beginning like that with that kind of hostility means I
sort of don't know how to reply! Further, you didn't express any real
concerns to me. I just figured you were mad and wanted to give you time
to cool off. Calling someone up is a way to explain over a higher
bandwidth medium gives material reiteration of a real honest heartfelt
apology in misunderstanding.

I'm only including more details in the email because you had deceptive
framing. I normally would *never* include contents in a private email
message and believe this is already the gray area. I already feel
uncomfortable publishing my message to you without permission, but I
feel it's necessary context, but I will not continue. Would you like to
have a public call instead? I really want to talk to you to express that
I really mean what's best for bitcoin. I've had a sleepless night
thinking about these things, this type of drama is *NOT* good for
bitcoin.

I came here with good intent, even with Core and Blockstream being
outright hostile and controlling with many personal problems over the
years which I have never aired previously. I can tell when I'm not
welcome. I'm going to take a break from all of this.
