Re: RFC: advise against using Proton Mail for Debian work?



Hi,

My few smallcoins, responding to each of the proposed outcomes (even
if they were intended to be mutually-exclusive...) are:

A) Educating contributors that retaining control of their signing keys
is important seems valuable -- it seems OK to provide a few
illustrative examples of situations where relinquishing or losing
control of keys could be problematic, and the reasons why.

B) To follow the security vulnerability disclosure model: it seems OK
to indicate that a given vendor is problematic for a specific,
communicable reason -- and beneficial to contact them first to
indicate the concern and ask whether they're aware of a problem and to
check whether they're willing-and/or-able to mitigate that.

C) If the risk is vendor capture of key material, then a similar
concern should probably be about vendors who provide functionality
that could lock contributors into their ecosystem for any reason.  In
other words: if the concern is about behavioural coercion or that an
entity may behave in future in ways that a key author might not
intend, then I'd argue that it's not only the author's key material,
but also the output communication styles and abilities allowed by the
vendor that should be questioned.  So: it's fine for a vendor to do
something to help Debian, but it should be in a way that any other
vendor can implement, based on a public, ideally DFSG-compliant,
specification.

Regards,
James
