Dear ndm,
You're talking to the same group that made a massively public modpack (tekkit) without permission from the respected mod developers. Of course they're not going to care.
They're just offering a service that makes it convenient to make a custom mod pack and send it to people for easy access. It will also allow for hundreds of mod developers to be pissed off that these bros are essentially promoting the usage of mods without permission by making it so easy. THE TRUTH HURTS DOESN'T IT?
