The issue ia clear and simple, it has to be a state initiative, and would eat heavily into the market share of current big players of the sector, and those players either have nothing to gain, assuming they tried to give their app actually good uses as wechat has, or they would distort it so badly that it would not change things meaningfully, it wouldn’t be similar to wechat. So meta and company will fight against it because social gain is not on their radar, but the US state has some interest in it because it might be one good tool to try to claw out of current and looming crises. But the issue is that they are in a somewhat soft position to bargain for it because they lean heavily on the big techs for propaganda, which is of essential value to the US government. TLDR capitalism is a mess, the state is less and less capable of keeping the bare minimum of social support to its people given the insatiable hunger for profit of the private sector
