The difference here will be the whether Parler was negligent. If they had calls for violence on their platform that were reported to them, and their community moderation team was so short-staffed that they didn't act on them, Parler could have culpability.
Facebook, et al have moderation mechanisms that can probably withstand scrutiny, but Parler sounds like an extremely lean operation that the discovery process may reveal to have negligently failed to act on information that led to death. It's not about people disliking their political speech, it's about them ignoring things they had a responsibility to act on.
