re: #22 Gus

I pay for email service, and think we’d all be better off if en masse we recognized there is really nothing “free” about goods or services we desire.

Most people pay for telephone services, which these days usually include data services and not just voice. Email accounts often go along with these services (or they can be added.) Same with the cable TV service.

Gmail, Facebook, Twitter - these exist as part of the larger world of advertising, as you point out. Enticing users with “free” is misleading, as in the end the price of goods and services people buy are loaded with advertising costs.
