I think they have a professional offering. You can give them a bit of your money to have a proper branding as you like, or just remove it. The cost-free version is not primarily meant for commercial use. Just stop thinking a company is non-commercial.
It is simply stupid if the companies prejudge a project in such a way, although there would be an offer for them, which is made especially for commercial projects.
Edit: but I see that there are not very much advantages when a project does it like they do at Anubis.
