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."
