My biggest gripes with headline and article that they used the term with extreme ambiguity. I'm sure 50% of the world companies are classified as "tech company". Every time I see those term popping up, all the question I have is tech in what? and What is their specialty? Espically with many new entities name and it is harder to track of what they do.
