Maybe news agencies aren't much interested because this is still only an early proposal, but considering its implications I find it striking how little it seems to be talked about on the web (outside of hackernews). Rossmann seems to be the only one with a video on the topic up on Youtube. There's only a handful of Twitter results for "web environment integrity api" with next to no replies to them. When I look the keystring up on reddit the only result with a noteworthy amount of debate is not related to WEI at all. Social media is probably just on its last legs, but it doesn't seem like too many people that care are left to fight for what the web, or even general computing, used to be.
