There Is No Free Money in Bitcoin
The fact that every holder of Bitcoin is entitled to his or her share of Bitcoin Cash tokens does not make it free money. BCH tokens will be issued at a 1:1 rate to Bitcoin. If you own 100 Bitcoin, you will receive 100 Bitcoin Cash. Those new tokens can then be sold on supporting exchanges, either against Bitcoin or fiat currencies. However, the value of these tokens may be effectively subtracted from the Bitcoin price at that time.
