Someone randomly spouting off that people of a race or ideology should be wiped out doesn't always/exactly pass this legal test.
I don't know what the exact legal definition of imminent is, but the layman's definition involves the thing happening soon.
It may well depend on how close to 5 it is (but what timezone?).
The same sentence with the words "right now" would almost certainly meet the test though (assuming the action was actually likely to occur).
E.g. "We should go harm X" is arguably illegal, since it's an immediate call to action.
However, "It'd be great if X died" or "All Y should die" are certainly protected.
In the same vein, this is why "Punch a Nazi" is totally legal: assault is illegal, but you're not immediately inciting a lawless action. "Let's go punch that Nazi", less so.
If you write a book advocating for violence against x or y group or individuals that is permissible, but if you were in a crowded square and advocated the same thing when those targets were also in the square and it is likely that your incitement will lead to violence then it is not. That's incitement, it's imminent, and it is for a lawless act. But again, if you did it at home on your blog in some nebulous sense that isn't likely to cause some specific event then it is protected speech.
An important distinction here is that "true threats" are a separate category from what we are talking about. A true threat doesn't have a "likely" or "imminent" component and so is even broader in scope than violent speech in general. That is, true threats are not protected.

The government is the entity that is not allowed to restrict legal free speech. Private corporations are not bound by the same rule; they can restrict all they want.
Or somehow UPS is different from a social media entity. Then what legally is a social media entity?
These are interesting times. The rules will certainly change; it remains to be seen if they will ultimately change for the better.
So in your framework, transmission of user content + advertising based on that content = culpability. I wonder if social media companies would figure out a way to legally prove transmission of a message without viewing its contents as a way to avoid culpability and maintain some level of profitability.
For example, calling for the murders of specific people based on their political views or races don’t fall under the first. And social medias allow the spread of some of these messages with no consequences at the moment.
