Picard just likes to be a self-righteous jerk (hmm, wonder where Janeway and co. got it from). NO CONTACT WITH PRE-WARP CIVILIZATIONS. EVER. UNDER ANY CIRCUMSTANCES. HURR DURR. I mean, weren't the Bajorans pre-warp? But that was okay because they were already "contaminated" by the Cardassians? I don't actually know that for a fact without looking it up, but if the Bajorans DID have warp technology then just lol.
Yeah, I love Data. Remember, he didn't die, that was just a bullshit Picard Nexus fantasy.
