We have a third option. We could define that the following part of Jb's
announcement ...

"We have come to the conclusion that continued innovation on Thunderbird
is not the best use of our resources given our ambitious organizational

and stability for our 20+ millions users, either individuals, SMEs or
large corporate/institutions."

"New messaging features in Thunderbird are no longer a priority for
