The people who formulated the ban failed a few times previously, both because they couldn't gain enough political support to push it through and because it was legally shaky. The Gaza issue was what led to overwhelming support for a ban in the US Congress and Senate (as Romney says), and the ban was intentionally formulated in such a way as to try to legally sidestep the First Amendment question (in a highly dubious manner, but the SC isn't going to overrule Congress here).
> mentioning democratic rights for a CCP app is hilarious.
It's the most popular app in the United States. Calling it a "CCP app" is just braindead. Of course banning the most popular means of expression in a country because the people are expressing themselves in ways that political leaders disapprove of is anti-democratic.
