- I'd say that symbmath is, in a crippled version not even having sine
- and cosine, is freely available on the net (as shareware), but not
- freely usable (shareware, you see!), is rekking pretty much like
- commercial use to me.
-
- On the other hand, seen in this light, every distribution of crippleware,
- or even shareware, constitutes a commercial use of the net.
-
- Strictly correct would be only the posting of programs which are freely
- usable for certain users (private users, non-commercial use, something
- like that). Most shareware may be tested a limited time.
- Distribution of such shareware is akin to an advertisement of available
- services, distribution of demos and crippleware even more so.
-
- How to cope? I mean, what constitutes commercial use if not distributing
- advertisements and free samples of not completely functional equivalents?
- What more must one do to qualify as a commercial user?
- The only difference I see to "commercial" use is that "commercial users"
- would maybe not distribute any test material. But this is definitely
- a deciding line drawn by hsareware authors only.
-
- The only other intervening rationale would be that the distribution
- of shareware should have some means, and the net is an obvious one.
- But then this should be restricted to shareware. I think crippleware
- distribution is really as commercial as things can get.
-
- I for myself got the crippleware version of symbmath and was not even
- able to decide whether this software could be of any use to me because
- it was even lacking trigonomical functions (this was, of course, the
- "shareware" version). So buying the software in a sufficiently working
- version would have been in my case buying the cat in the sack, not
- shareware at all. I solved my special problem with an own program,
- and up to now do not know if sm could probably have done it.
