Thank you for your responses (I genuinely mean that) it’s good to have a discussion on this and I totally understand you have to draw the line somewhere.
Based on this we have started the gears moving to migrate away from OwnCloud. Again, I don’t mean to sound like this is a threat, it is not 
I just wanted to inform you all that this was the deal breaker for us and so we will be migrating our users over to something that is supported in the OS that we use. I don’t know if you keep track of this information anywhere but wanted to at least put it here.
Thank you again.
