A: X company is shutting down development on their web software product.
B: X company is shutting down development on something.
C: X company is shutting down development on their web software product, which is used for collaborating on software development.
Then I bet that if your friends find any difference at all, they will rank C better than A better than B.
The headline alone tells us B, and the headline plus the LAMP comment tells us A.
