TY anon.
For some weird reason hsdl.org resolves to 127.0.0.1 for me, kek.
No luck with archive links either.
At a quick glance, on page 19 the section on foreign influence is redacted, but footnote 154 that goes along with that isn't.
So to me it looks like at least some suspect he was working for foreign intelligence, associated with HK in particular.
