The latter group often spend quite a bit of time fixing broken alignments etc when picking up a Sketch file that's used Anima. This means everyone is forced to install the plugin. The other issue then is when pushing to Zeplin, many elements aren't aligned as designed regardless of whether we've got your plugin enabled or not.
It doesn't happen every time, but it's happened enough times to warrant a studio-wide disabling of the plugin. I don't know if it's possible to easily solve this dependency issue in a future release, but if you can, we'll certainly start using it again.
