Parler does not want to moderate their platform of violent rhetoric, because their customer base is there to engage in violent rhetoric. If you think Parler should have the right to allow their users to continue to threaten violence to people, well, that's still not a slippery slope, because there is no precedent being set here other than "Amazon will not allow unmoderated calls for violence on their platform."
Amazon always will, and always has, had the ability to terminate users for just about any reason. This is not them doing that, since they've provided a clear solution for Parler which is "stop allowing your users to make violent threats", and they've provided apparently an abundance of examples. Examples which Parler has not taken action against.
For many services with millions of users, if you keep your head down, it can take them quite a while to notice you're in violation of your contract... but yes, if you make a bunch of people angry, one of those people is going to notice you're on AWS, pull up the AWS AUP that's published right on their website, see that you're in violation and report you.
This should be obvious to everyone. The AUP is not a confidential agreement.. and everyone can see where your server is hosted.
The article seems to suggest that it's calls for violence that have violated its ToS (presumably agreed upon at time of hosting or earlier).
> it seems pretty obvious that this did not happen because of the simple facts in evidence regarding Parler, but because of the broader context that a lot of people were beginning to try to pressure Amazon to drop Parler.
So I don't see how what you say is indeed obvious, since Amazon's relationship to Parler suffice to explain the termination, absent any public sentiment or pressure.
Perhaps your argument would be bolstered if you can provide an example of a service with similar volume of calls to violence that has not yet been booted off.
That's capitalism in action. ¯\_(ツ)_/¯
Sure you can. Even if some of the circumstances will be different, it seems pretty obvious that this did not happen because of the simple facts in evidence regarding Parler, but because of the broader context that a lot of people were beginning to try to pressure Amazon to drop Parler. One could easily envision how this could also be successful in future cancellation campaigns - if a company makes a mob outraged and the company isn't going to reform on its own, then one can naturally escalate the deplatforming effort by going after any company-related apps or service providers. Do we really think this isn't going to happen absent a riot? We already have the rhetorical justification: "This is just private actors showing you the door."
