This explains much better what you mean than your first comment. While I somewhat agree, I think that ship of using the wrong label has sailed long since. Which sells better: calling yourself a tech company, or a mercenary manipulator?
I think the comment you were replying to basically agrees with you, they are imputing that Facebook and Google are the ad companies. AMD, Intel, even NVIDIA (although they are feeding on a bubble that might eventually roundabout end in ads), those are tech companies.
