To expand on what @Michał Masłowski said. The Developer Meetings[1] which
were a consequence of some mid-2012 work[2] by @Chris and others were a
response to similar discussions 2.5 years ago and the matter is in hand with
the new contribution / community system being part of the response. (Yes it
really does take that long to develop/modify and bring online a significant
new system).
The need to join trisquel-devel so patches can be accepted is clearly
documented in the package helpers page[3].
As I've said elsewhere on the forum in the past, to me, allowing for the fact
he his extremely busy and massively overcommitted, Rubén's communication
style seems to be simply be a very hard pressed flavour of what is documented
of geek subculture by e.g. ESR's essays (although beware their quality ain't
great, see [4] and mind the 'hacker' misnomer). So quidam's comms are not
good by non-geek standards but are an understandable and rational response to
the situation within the context of the subculture.
I think the linked reading is about all you need to have an informed
discussion.
