Actually, it appears they had given them plenty of time to implement proper moderation practices to prevent incitement of violence. Their response was inadequate. They were removed from Amazon.
You seem to imply they only got 24 hours to resolve the issues on their service. That's not accurate.
Incitement of violence isn't measurable. The US had autonomous zones and communication was allegedly through Twitter.
It is a cheap excuse to take blame from the actual perpetrators to inconvenient platforms.
I like unfiltered platforms very much and Parler wasn't that attractive, so I appreciate them being the fall guy. But I also have problems with blatant different weights that are used to measure transgressions.
From Amazon’s POV, the same sequence of events may look like this: people were kicked off from Twitter; they sign up for Parler; the amount of insurrection planning on the platform skyrockets; FBI starts calling Amazon; leadership decides they’ll rather take a lawsuit than risk being involved.
