To add to the discussion about plagiarization and misinformation, one thing I know that can contribute to complacency is how much time and effort it can take to fact check everything you watch. That's daunting for most people, let alone people who don't have as much experience with it or who deal with disabilities and executive dysfunction.
But there are some things you can do to minimize damages that are easier to manage on a more individual basis.
You don't have to necessarily fact check every single thing every creator says in every video in order to make sure they're 100% legit every time. I know not everyone has the mental bandwidth to do that sort of thing constantly. Generally it's okay to just practice some mindfulness and not blindly trust someone if you haven't vetted their claims personally.
What you can do is fact check yourself. Don't repeat stuff you hear from a video as if it is a fact unless you have looked into it yourself first to confirm that what the video said about it is true and that their sources are good. And if you source someone make sure you've vetted them specifically and checked their own sources on that particular topic or bit of information (and check that they even HAVE sources to begin with and aren't just copying their sources verbatim). You can't source every video essay you ever watch or check every single one for plagiarism, but you can source yourself and what you say, and make sure you're not spreading bullshit or citing the wrong person. If you find that you don't have the energy to do even that much in a given moment, then just keep the information in question to yourself for the time being until you do have the energy to verify it.
And some stuff that's generally just good practice: if it's a topic that you're particularly interested in, it's a good idea to seek out more than one video about it from more than one creator. The more diverse your sources of info on the topic the better, especially if you seek out more than just the popular stuff. Get a broader picture of it from a wide variety of people from a wide variety of demographics. It's a lot easier to spot stuff like plagiarism if you're looking at more than just one or two channels, and even if you don't spot it, because they're often good at hiding it, you at least can make sure that you're giving more obscure creators the same attention as well instead of only defaulting to the most popular wide-spread creators and content.
Seeking out more than one type of medium is usually a good idea as well. I know reading stuff like written papers or essays or books on a topic can be difficult for some people, but if you can manage it even just occasionally then branching out every once in a while is still worth doing because it gets you out of one particular information sphere and into another, reducing the chances of an echo chamber effect. If you can't bring yourself to do that much homework on a topic, then again remember to keep in mind that your knowledge about it is limited and could be wrong, and don't spread that info without doing your own research first. Videos are not inherently a bad way to learn about stuff, papers or books can be wrong, and plagiarized, and badly sourced, and can spread misinformation too, my main point is that it's good to avoid having your information come to you through a single choke point if you can help it.
It can be exhausting trying to hold every online creator accountable on an individual basis, I get that, so I don't expect everyone to extensively peer review every channel they ever watch, but at the end of the day you can at least make sure to try and hold yourself accountable first and foremost.
