Do You Think That Small Booktuber's Aren't Credited Enough?

This question came about after I came across Emmy Rosam's latest video around using a wheel generator to choose the books she buys. She states in the video that she "can't find the comment that gave this idea". Which I was like wait a minute I saw this video idea from another small YouTuber. So when you search for "wheel chooses the books I buy" it instantly comes up with the only other creator to have done this video done by a small booktuber - Katerina:

Now I am not saying that Emmy purposely didn't give this small booktuber credit for the idea, nor was this small booktuber the founder or deserves the credit. However, with only two videos out there on this unique book shopping vlog and Katerina's being the first (from what I can gather), why wasn't she given credit? Did Emmy just not take the time to look besides her comments?

This is a general conversation as well around small booktuber's who come up with unique videos and then you see bigger booktubers who will use those ideas but never even think to give credit to the ones they may have gotten the ideas from. This isn't the first time I have seen this with big book influencers and it won't be the last.

But I just feel bad for small book creators like this one that may have put in the time and effort to create a video that was unique and someone else comes along doesn't give them credit and uses that idea getting more views and "wow that was such a unique idea". This may be silly or nitpicking. I am curious to everyone else's thoughts!
