Linux edition needed or at least online method

I have an old Mac that is now out of life and recently switched the OS to Ubuntu Mate.

From a lot of Google search as well as forum search here, it appears that ADE is not available for Linux. 

I understand the business case for this however present information available to all suggests that world wide Linux has a greater share than Mac.  If there isn't going to be a Linux ADE, is there a method to do the same online?

As per many posts, downloading a library book (where I paid a fee to join and assume many others do as well) I want to read on my ebook should not be held up by the commitment to Adobe Digital Editions.  My opinion only.

If you were to create an online version of this (and if you do, I certainly could not find it), I for one would pay a small fee to purchase the service.

I look forward to the reply and the input from the community.

Thank you.

PS.  I understand about Wine...it is not my preference to use that as a non techie.
