I'll spell it out for you since you can't read between the lines. It's not actually about fire-keeping in tribes to protect children. It's about certain people (governments, corporations, organizations) wanting control over the Internet and everyone's digital communications. They don't want a free marketplace of ideas and uncensored channels of communication because their propaganda narratives would not survive.

The tribe leader refers to certain rich and powerful folks that have infiltrated governments and are running some of the largest businesses.

The fire refers to instant communication over the Internet. This relatively new technology has the potential to paralyze old power structures and reshape civilization. It's understandable why governments et al are panicking. They know their authority will wane under global free speech unless they do something.
