The US government isn’t banning it because it is worthless. This isn’t about the content in any way. It is about the collection of data by a major foreign power and the use of that data to feed specific propaganda to US government personnel.
My take on it is unless the US government is willing to formally show proof it is direct foreign propaganda they should not be allowed to ban it and the bar for that proof should be HIGH.
Slippery slopes and all..
What keeps the next president from declaring CNN or Fox News or Google or the AP “propaganda” and pretty soon government devices will be a stupid shitty battleground for cheap political points and not safe work devices.
