This has definitely played a huge part. I've mentioned it before, but if you haven't watched the social dilemma, then go and watch it. Social media has completely automated systems designed to keep you scrolling or coming back for more. There is zero regulation. You don't even have to click on a link, they will analyse how long you stop scrolling to look at something and that feeds into the data. The algorithms then provide you with content it thinks will get you to click. So if you click a conspiracy video on YouTube, YouTube will just send you more links that are similar. It's so easy with social media to get into the conspiracy black hole because they social media sites are actually sending you more and more links regardless of if they are appropriate or false. There is no human element in the process to question whether it is the right thing to do. It is simply an algorithm getting you to keep on clicking, regardless of the damage it does.
