My company hired a web agency to build the company's website and the online presence through social media.
The first video that the web agency made (A video previously produced by the company but re adapted for use on social media by the web agency) had the logo of the agency at the end of the video and not in a very discrete way. Wen we talked to the agency to say that we'd prefer if they didn't add the logo at the end of videos, they refused saying that the agency should be the "mirror of the company" and that keeping their logo is a sign of "mutual gratitude" (not sure what that means).
Do web agencies have the "right" to add their logo in clients material? Or is it even a convention for companies to let their web agencies add their logos?
