What? I found it informative - clear and to the point about what frustrations you can expect with the licenses.
I mean, FCOL, he even made the effort to search google for the cost of the licenses because Franz hides them.
What exactly in the following texts do you describe as "strong anti-commercial comments"?
------------------------------------------------------
> Moving to proprietary implementations; Lispworks has been around for more than 30 years and the company producing it still release new versions on a regular basis.
> While Lispworks supports most features you would expect from a commercial product (native compiler, multithreading, FFI, GUI library, various graphical tools, a Prolog implementation…), it is hampered by its licensing system.
> The free “Personal Edition” limits the program size and the amount of time it can run, making it pretty much useless for anything but evaluation. The professional and enterprise licenses do not really make sense for anyone: you will have to buy separate licenses for every single platform at more than a thousand euros per license (with the enterprise version being 2-3 times more expensive). Of course you will have to buy a maintenance contract on a yearly basis… but it does not include technical support. It will have to be bought with “incident packs” costing thousands of euros; because yes, paying for a product and a maintenance contract does not mean they will fix bugs, and you will have to pay for each of them.

Releases are uncommon, the last one being almost 6 years ago. But Allegro is a mature implementation packed with features not easily replicated such as AllegroCache, AllegroServe, libraries for multiple protocols and data formats, analysis tools, a concurrent garbage collector and even an OpenGL interface.
Allegro suffers the same issue as Lispworks: the enterprise-style pricing system is incredibly frustrating. The website advertises a hefty $599 starting price (which at least includes technical support), but there is no mention of what it contains. Interested developpers will have to contact Franz Inc. to get other prices. A quick Google search will reveal rumours of enterprise versions priced above 8000 dollars. No comment.
