They are 8 people in the dev team. How People cant understand why they dont want to comment on this particular matter is beyond me. Its not worth the death threats and irl-targeting, and its not worth the potential sales loss for a super-small indie team that has been working on this game for over 5 years.
This as well is probably a factor.
When Playtonic removed Jon the devs had to make their twitters private, even Grant Kirkhope, who has spoken to and seen Jon personally.
Update: Apparently Grant hasent been in contact with Jon in ages according to his twitter response.
