1) This tool is made by an Alphabet owned company (Jigsaw), not Google, another Alphabet owned company. The companies will have different missions, even if profits flow the same direction.
2) Venezuela doesn't have a huge market where Google is blocked by a nation-wide firewall.
3) China has a nation-wide firewall blocking any Google service, thereby forcing Google to negotiate how their service works if they want to make money there.
Note: Oversimplifying the situation for the sake of pitchforking a company you might not like does no one any good. Venezuela and China are very different companies, in very different environments. Google as a company (and Alphabet, probably more so) is almost certainly anti-censorship, philosophically; they just don't operate in a vacuum.
