I have a simple rule of thumb. If the license is restrictive of my work, then I do not use the product. If you have any doubts about why, just think in terms of IP. People get burned all the time because party A (who owns the license) decides to lay claims to party B's work (who merely bought a copy, or signed a contract). At which point, B looses automatically. I realize that most work (today) will never have that done, but who wants to be the victim of robber barons?
There is to much out there in the world of open source to say that one is locked into a solution like that from the start. The decision may unfortunately not be yours at work, but at least it can be yours at home.
btw.... I do not use ActiveState products or M$ products to develop. I use open source only.
