I'm fully aware that I could simply move some discussions to a ship, flashpoint, ops chat, use mail or combinations of them to pull off that 'private' conversation. It's the principal.
What many people don't consider is the actual setting.
If I'm stood in the middle of an Imperial building - that has machinery inside, perhaps other people talking, droids walking around.. Then someone pressed up against the wall outside (taking advantage of the large /say range) isn't going to be able to hear a thing.
That's the first thing.
For me. Roleplay is all about the people around you, not you - yourself. I have no problem at all for someone to pull me up over something they'd heard ICly. I do however see it as a little .. insulting perhaps, to be be in an "empty" room with someone hid in stealth either just outside, or just inside.
That to me doesn't seem like good roleplay. Like someone earlier said, you're essentially power emoting. Forcing that situation on the characters there by saying "I am here, and I'm going to use this information."
At least how I feel.
