Apple is removing older versions of its software from its Purchased Tab on the Mac App Store.  Software such as previous versions of Mac OS X, Mac OS X Lion, OS X Mountain Lion,  OS X Mavericks, as well as Aperture.
The decision to do so isn’t going over well with some users of reddit, which the web site has called some of its user’s comments as “user-hostile.”
One user commented:
“That’s really unfortunate and hostile by Apple. What about people who use older operating systems due to compatibility problems with specific software?
I recently had to re-install Mavericks, but didn’t keep the “Install OS X Mavericks” app. Now my only chance of getting it again is to download it from another location, and I don’t know whether that image has been compromised.”
No official word from Apple as to why the company is doing this.
