The comment I replied to does NOT mention hosting free software by yourself, a route with which I agree if you're so inclined.
The comment I replied to mentions preference towards Ads-enabled services, just because they are free of charge and when a subscription to a service that keeps your data is the same price as 2 coffees, that's being a cheap bastard dude.
Also, in case this term offends anyone, it wasn't really meant to be insulting. As I said, I'm a cheap bastard myself. For instance I take advantage of a lot of available freebies, like Heroku's free dynos. I'm also a free Google Apps user and haven't made any attempts to escape Google's silo. Nothing wrong with that. But in regards to the price you end up paying, sometimes cheap stuff ends up costing more.
