The situation’s a little more complex than that, but…

Well yeah, it’s a funny chicken-and-egg problem of defaulting to trusted when not having sufficient access to check for “mark of the web”, due to running with lowered privileges to reduce attack surface…

Well, that and allowing active content and network access at all to be triggered from what’s “supposed” to be an ad-hoc offline copy of web content, let alone not very restricted filesystem access, but I suppose that’s probably A Feature(tm) and not a bug.

Fascinating, isn’t it?
