work-alikes

The overwhelming majority of Linux window systems and desktop environments were Windows 95 work-alikes, NeXTstep work-alikes, or attempts at minimalism based on BlackBox or aewm.

It does and it has lots of work-alikes on other platforms (though some are not nearly as good).

A Purify patent prevented work-alikes for many years, but valgrind eventually emerged as a more-than-worthy successor.

Free Software (and proprietary) alternatives and work-alikes for each exist, and in many or most cases are more successful, though AD remains a market leader.

Either way, expect no HyperCard (or work-alikes) from Apple.

The business model was to charge for privacy focused work-alikes of popular free utility apps as an effective luxury privacy brand for apps, but even this misunderstood luxury products (an area I had some experience with, in addition to security and privacy).

There are free and paid but lower-cost sorta-work-alikes to both of those apps (and I even use them sometimes -- RawTherapee in particularly has some nice features), but nothing I've tried free or otherwise comes close to the overall feature set in those two packages.

"The overwhelming majority of Linux window systems and desktop environments were Windows 95 work-alikes, NeXTstep work-alikes, or attempts at minimalism based on BlackBox or aewm." The majority of existing Linux window managers are not representative of the window managers that the majority of Linux users actually use.
