You really didn't need to mention that and direct his clients to someone else just because it's free. People need to respect quality, graphic designers have this problem also and believe me, people offering things cheaper or free doesn't mean it'll be just as good, little do people know how far graphic/intros get you if they're done well. Especially intros, the first 15 seconds is the most important part of your videos and an intro is a big part of that. With graphics/gfx, if you goto someones channel and they have an amazing banner on their channel, you'll most likely scroll down to see more and maybe even subscribe if you like the look of his channel.
Anyway, went a bit of topic but as a graphic designer myself, it frustrates me, sorry
