I'm maybe naive in assuming that there is some kind of investigation going on that isn't playing out in public, but I would assume that years of emails going through Microsoft servers might make the identities of the cohorts in this attack difficult to hide?
When making sockpuppet email accounts use a plausible birth year as your numeric extension.
In the OP, many of the links (e.g., "first, innocuous patch") lead to mail-archive.com. From there, click the button with the name that appears after "Reply via email to", and it will open your email client, with the To: filled in with the email of the person.
I couldn't spot email addresses directly in plaintext for those who weren't submitting patches (e.g. Jigar), however if you look at one of the links to his (?) responses then there's a mailto link with the text 'Reply via email'
