Why is EndNote not available for linux yet??!

Hi, 

Any academic who is worth their salt in physics or math is a linux user. 

Why has endnote manager not been ported to linux yet (ie Ubuntu, etc)? 

In the forum history users have been asking for this since at least 2008!!

Mendeley is available in Linux but I find it very frustrating to use (sync issues, slow pdf search, sync doesn’t always work, etc etc).
