Jandhyala is the author of the book The Great Disruption.

When Wikipedia was founded in 2001, the idea that people around the world could come together to create an accurate online encyclopedia covering virtually any topic seemed far-fetched.

Cory Doctorow, author and digital rights advocate, argues that big tech companies from Facebook to Google and beyond have evolved - or devolved - in a disappointing way. He says that many large tech companies begin with a good product, but that over time they prioritize first business customers, and then ultimately shareholders and profits over end users.

Doctorow wrote the new book Enshittification: Why Everything Suddenly Got Worse and What to Do About It.
