The AWS name wasn't associated with Parler and the Capitol insurrection, but it likely would have been. This is all about getting ahead of the story and limiting any potential brand damage.

It's similar to when Cloudflare booted 8chan, after the latter was linked to the white nationalist terrorist attacks in Christchurch and El Paso.

I don't understand the rationale for your view. Why would slapping down a potential Twitter competitor be any concern of AWS?
