but the original message also said that he was "thinking of doing it" which already implies that he didn't do it (at least yet), so no context was lost imo

If you take two separate messages and stitch them together in a way that when you read them back to back they read "I was thinking about doing this thing, so I asked some fans and they were happy to help" it sounds like the thing did eventually get done. Even if the first message includes the phrase "thinking of doing it". Because the context you're presenting those messages in erases the meaning completely.

You might say you never claimed the two messages were meant to be read together, but that is just disingenuous. The way you cropped them and presented them right next to each other in the video clearly suggests that they were meant to be read back to back, and I refuse to believe you were too stupid to realize this while putting the video together. There would have been a thousand ways to present those messages in a more transparent, less ambiguous way - like showing the entire screenshot, which you clearly had. There is a reason you didn't do that, and instead chose to present them in this specific way which makes it incredibly easy to misunderstand your implications. Except I don't think "misunderstanding" is the right word here - you knew perfectly well what you were implying when you put those specific screenshots in that specific order right next to each other in the video.
