Why Didn't Ripley Tell the World...

Somewhat of a simplistic question, and I have my on ideas, but after Ripley comes out of cryosleep in Aliens, why doesn't she tell the world about what happened to her aboard the Nostromo? Also, wouldn't she be somewhat of a celebrity? I can't imagine many people who lived after being in cryo for 50+ years. My ideas: 1) If Ripley were to/did speak to the media, the Company obviously waas powerful enough to control any story released; 2) The Company painted Ripley as mentally unstable, so no one would believe her; 3) After hearing that there were colonists on the alien planet and no one had encountered any alien in all this time, perhaps she herself felt that maybe she was wrong/crazy and hesitant to speak out. Thoughts?
