A few ways of looking at "free" services.
1. Price is what you pay; Value is what you get.
2. Anything offered for free usually comes with a "catch".
3. Always look for a hidden catch.
4. In God we trust, all others pay cash.
5. He who pays the piper, calls the tune.
6. You should not be a "bludger".
7. If it's free, who is carrying the cost.
