@zzt Hey, just to clear this situation up:

We received the donation out of the blue with no knowledge of who these people are. We don't have any communication with them and don't know what (if anything) they want from us. Maybe they just want more traffic to their site, which is mostly about software.

Our rule is donations cannot come with restrictions/requirements/influence other than we add a logo to our site. They requested this. At the moment we have to follow our own bureaucratic rules.
