That text is quoted from Section 230. The reason Section 230 was introduced is that, long ago, if platforms did literally any moderation on their site, they were considered to be taking an editorial role and liable for all the things they failed to moderate (e.g., if someone posted libel, the platform would have liability for it), so there was an incentive not to moderate at all, because you wouldn't get it 100% right. For pre-online platforms this was fairly reasonable (e.g., you could hold a newspaper responsible for its columnists publishing libel) but it put a serious damper in real-time user-contributed online forum. Section 230 said that if a platform acts in good faith for those moderation reasons you list, that doesn't cause them to gain liability - they're still in the same place as if they didn't moderate. If they exercised active editorial control, then they'd be responsible (e.g., you can't just host a pro-harassment forum and solicit other people to post harassing comments and expect Section 230 to protect you), but as long as you only do normal moderation of obviously bad stuff, you're fine. This draft executive order says, we're interpreting that part of Section 230 to specifically not count "deceptive or pretextual actions restricting online content" as normal moderation, presumably including things like flagging Trump's tweets for misinformation. That leaves Twitter with two choices: 1) forfeit Section 230 protection and be responsible for all the content on their site (i.e., they'd have to heavily and reliably moderate every single tweet) or 2) stop flagging Trump's tweets for misinformation and do even less moderation so they maintain Section 230 protections.
