with death note in particular, i think a lot of people also get confused about what is/isn't canon because people just don't know where certain pieces of information come from. this happens in all fandoms but it's especially bad with death note because relatively few people have read the entire manga as their primary source, so it's easy to assume that extra-canonical material comes from there when it actually doesn't. you can kind of make an argument either way about whether or not labb or htr13 or the short story comics should be considered canon, but there are a lot of things being passed around as canon when they just unambiguously aren't. for example: L's monster speech is from the alternate canon relight series, the line about L and light waiting for each other after death is from L change the worLd, which is a novelization of the japanese movies rather than the manga itself, mello finding soichiro cute is a quote from ryuk in the htr13 'ryuk's observation journal' (ie ryuk is the one saying he finds soichiro cute), misa's suicide is from an o&o interview where they speculated about what they might have written if the story continued. it isn't an alternate interpretation, they're literally just not from the series
