Let's make sure we're on the same page here:
1) Talisman doesn't "suck". It is an excellently written piece of software IMO. It is a very good program.
2) I don't think that LightTek is doing anything that they feel is underhanded. We all have different thresholds of what we consider acceptable policy in terms of using other people's resources. LightTek, for instance, uses Download.com's animated download button (not the editor's choice but their internal one). I don't have a problem with that. Another person might. I talked to Jark and he doesn't have a problem with them linking to the files in the way they do because it still counts as a download on dA even if it doesn't explicitly show that they're getting the file from dA. I, on the other hand, would have a big problem with a commercial company linking directly to files here without our license.
There is nothing illegal in what they're doing. I just personally find it distasteful since I'm aware of how expensive bandwidth is. If Jark doesn't have a problem with it, then everything's fine (and he doesn't have a problem with it). I do, however, still maintain that I bet that Mian and Chaz and others might have a problem with it (especially since they're not even linked to on the partners page).
