This line severely damages the credibility of the article. I found the article interesting up until I read it. I stopped reading once I read it because I couldn't trust anything else the author says.

I highly doubt this statement is true. It may be true in very privacy-focused circles and amongst some circles of IT professionals, but I highly doubt it is true for the population.

If you make a statement this left-field, you've got to back that up with credible research and I highly doubt that statement was based on any credible research.
