Sure, but it seems pretty irrational to suddenly say 'Hey guys, we've been working on this code without telling anyone, so this community project that people have been working on for months should be abandoned'.
They could have been integrating the changes in their code as they went, and then launched with 'Hey, we have this cool new project, including the optimization work that people have been doing'. Instead, they kept their work secret, knowing that their work was incompatible with another large refactor that people were contributing to, and then said 'hey, abandon all the work you were doing because who cares'.
