I do not claim that you stole my idea, I am happy that it was used by you, and more people can learn from it. I just like when the sources are provided (especially when I am the source 😄). Either solution (reference in the description/ pinned comment) works, I do not have any preference.
I would argue on that, I think the resemblance is still striking. If you took a poem and added your commentary after each line, because "it seemed vague" it would still require a citation. But I do not want to make more fuss about that than required, so let me stop here. I hope your channel will grow. Thank you for understanding, and have a good day.
