I understand all is a matter of priority in development and I would personally give the priority to an android version, so much convergence and share between computers and android devices are growing fast.
I would stress however how much those exe files have their own advantage apart from sharing.
At a moment when I’m still confused with using version 2 and before making the step from 1.7 on my other computers, I’m glad I can still open those exe files no matter which version I have… or not yet.
For encrypted archive you don’t use on a daily basis it is nice to think it may still work the day you will need them while the software is no more available (or gone to a full paying version :) )
I am glad to have some of those “exe” files still running after few years when the software is no more available, even if it is not about encryption.
