These are just my personal opinions and are not necessarily based on the writing quality of each character.
It's not only this one comment on one video that too spread the same false theory as a "canon fun fact", misinformation like this is all over the place and it gets worse as even when I called this out, the commenters just double down on their point without displaying any sort of reading comprehension and seem to even understand context clues given in the story; and this is very misleading to newer individuals in the fandom who don't verify this and then spread it further as canon.
You have the "Tengen, Shinjuro and Urokodaki were actually there to kill Nezuko Muzan came", "Kanae died the day Sanemi was about to confess to her", "Shinobu told about her plan to everyone except Giyu", "Muichiro died in his birthday" etc. and all these are just either straight up false or not confirmed to be canon and are just headcanons being claimed as canon. I will be making a long post soon debunking all of these so please feel free to drop any other false "fun fact" in the comments so it can be debunked.
It's fine as long you don't claim it to be canon, and clearly state it to either be a headcanon or a theory, but please don't label it as a canon fun fact.
The worst part is that often Google takes up this clear misinformation and gives it as a reply in Google searches on these sorts of questions which people believe to be true but Google is not taking context clues into account and sometimes takes information from unreliable sources, which probably is not a big issue in itself but people just Google this false statement and give the Google generated reply as apparently canon evidence.
So to all the people in this fandom, please call out any such misinformation and verify any statement from the source material or fan books before spreading it further.
