Why was the title cropped here? If you're going to explicitly name companies don't you think all should be named? The title is implying other companies (i.e. Microsoft, Yahoo, Twitter, etc.) aren't a part of this. Maybe it should've been along the lines of "major tech companies including..."
The poster updated the title. I would agree with you but article's title named 5 companies and the poster's title named 3. Either copy the title in it's entirety or don't name any companies.
Edit: The title has since been updated.
