> This phrasing seems to suggest they think they invented the idea of "TikTok but it's Wikipedia". I see the author is OP, so my suggestion might be to consider rephrasing a bit as it comes off a bit accusatory.
Am I missing something, it comes off as the precise opposite to me? OP wrote "I built X, but the idea came from this source" basically, acknowledging they built the thing but the idea came from somewhere else.
Some of them came before me, but most of them were clones that came after me. I just wanted to highlight what happens when you go viral - there will be copycats.
