*nitpicking hat on* Tony did tell Peter about the SHRA, well in advance. Of course, then none of the writers actually did anything with that, so I'm not sure what the point was. *nitpicking hat off*

But overall, yeah, we're talking about the guy who once mindwiped everyone on the planet who knew his identity. Tony has a number of virtues, but being open and honest with the people around him isn't one of them.
