Actually, this isn't true: Tor with private Snowflake bridges can be very effective against the Great Firewall. I'm an activist who works in this area and I've spoken with activists who were using it as recently as this year.

The issue is scaling bridge discovery, since any automated bridge discovery mechanism rapidly exposes available bridges to a determined censor. But any team doing high profile, notable, or sensitive work can find an individual or organization outside China to provide them with private bridges. So Tor is one effective option now for key activists in China, just not a mass-scale solution for everyone.
