Earlier quoted context omitted.
You know what they always say, when something is free, you are the product.
This phrase should be put down with a shot in a back of its metaphorical head. Whisper Systems, TOR, tox are free. Should we apply the same principle to those products? (I am not defending this shady VPN service)
Free software is write once and release; it costs the author nothing to maintain it. Free services require maintenance and incur operating expenses that need to be covered somewhere.
The original quote was always about SaaS anyway.
