So I don't know what topic you're on about but the one you replied to I do. And in that context, these two statements unfortunately do not add up as the second one is a huge stretch from the first.

The misinformation in context (Russian propaganda, probably on rt.com or something) is designed to mislead. Not inform; mislead. This really is two steps further than a discussion between two equal discussion partners who disagree. A healthy discussion like that is based on arguments which are supported by premises. Russian propaganda is based on bullshit. It tries to spread as much bullshit as possible, then see what sticks.

Defaults should be reasonable for the general public, the average user. They should be harmless. The term used for that nowadays is SFW.

You don't want NSFW content by default; a search engine should by default remove that, but leave the option open to the user to do sift through it. For example, you don't want naked ladies on your screen at work or at home (if your wife or kids are parents are watching it might turn awkward).
