Technically true, but this is not really about terms of service or about "spoofing identities of non-consenting parties." This is about Google and Amazon not wanting to become collateral damage and lose business in those countries.

Signal is/was connecting to Google or Amazon servers with an HTTP Host header of google.com or souq.com, respectively—and only in Egypt, Oman, UAE, and Iran! Google and Amazon could have easily allowed this or even looked the other way.

So basically censorship worked, albeit not how we thought it would. Sad for people in those countries who were relying on Signal for private communication. Who will stand up for us when we lose ours due to some business decision?
