I think digitization, specifically the commoditization of attention in advertising-supported social media, has strongly incentivized bad-faith communication. It turns out that outrage and conflict are a great way to get attention. So systems made to profit from keeping attention have inadvertently started promoting conflict and outrage to capture the value of the attention produced. This has been profitable enough that these social media now dominate a large part of public discussions, and other platforms have followed suit either by choice or by selection pressure. Hence a large part of public communication is happening in a context that is (inadvertently or intentionally) built to encourage conflict and outrage. This rewards bad-faith communication, so that is what we get.
