This is a very touchy issue, only to be entered on with trepidation. You can see that some people are getting upset already. Still, I'll jump in with both feet as usual. I have some passing sympathy with the original post, though I don't know why I should be the slightest bit concerned since I have no commercial interests, and so these restrictions don't affect me. I guess it's just that gifts with strings attached never look quite so nice as gifts without strings, grateful though one may be to have them. Equally I completely understand and empathise with Mason's point of view here. I sometimes wonder what would happen if someone started posting things with really silly or offensive conditions: "This item is free for use by anyone who sings the Chinese National Anthem in the local park at 7 a.m. every day for the next week;" or "This item is free for use except that Jews require written permission from the artist". Would people use them? What if they were very nice things, too? But any discussion of these things is seen as biting the hand that feeds one. Never forget that all the people who post their work in the Free Stuff pages are really really wonderful folk whom we should praise constantly, for if you offend them (and some people round here are easily offended) they will pack it in and take their toys with them :)
