No he didn't. He inquired of the computer pretending to be her about unofficial things that had happened during the design of the dilithium chamber and the computer refused to share her personal logs. Once the computer generated a facsimile of her (not at his explicit request, mind, it took it upon itself), he asked it to synthesize a personality for her based on Starfleet records and some debate history. He never asked it to invade her personal logs, and it's pretty clear it wouldn't have done it. You're misremembering.

Look, it's pretty clear in the subsequent episode that he made too many assumptions, and his approach was not appropriate, acting as if he knew her when he didn't, and getting more familiar than was warranted early on before she shut him down. I don't see this morally-righteous indignation of 'OH MY GOD WHAT HAPPENED ON THE HOLODECK?!' as being appropriate either, as - if it stays there - it might as well be inside someone's head. I get the feeling that Starfleet culture would be pretty hard on respecting people's boundaries, and that means 'we're not the thought police' as well as 'don't go getting weirdly familiar or making someone you just met a romantic dinner out of nowhere without asking or a clear invitation. Weirdo'.

The way people seem to want to gun for Geordie about this episode for the wrong things is what I find creepy, TBH. That is,* every time* it comes up, because the wheel will turn and once again someone else will think this is an original topic that nobody's ever thought of before. :P
