Thunderbird voting showing how this shouldnt be something considered for non-trivial decisions. other word its not rational to make voting on for e.g “Do you want Tor or Clearnet in Whonix?” and if ppl voted 100% for clearnet then oh yeah then lets remove Tor.

I don’t think the poll was about “Should we remove thunderbird from Whonix if users do not use it”. Maybe ask "Do you use webmail or Thunderbird with Whonix. Or maybe “Do you use anonymous email with Whonix?” would provide more precise feedback on user habits.

Edit: Polling user on whether they use webmail or Thunderbird might be a good idea. If a large majority use webmail we should try to better educate them on this?
