What if BA is short? He wants the stock to go down. So he points out the negatives.
You are long. Obviously. You point out all the positives, to make the stock go up.
Who's worse than the other? You both have your reasons for pointing out your respective points, no? You are both taking a risk. You are both putting money on the line. You are both posting what's on your mind.
If a company is a great value, you go long. If a company is a flaming POS, you go short. Welcome to the stock market.
