In the latest episode of 'Loud in Tech', Rui Ueyama, the creator of the Mold Linker, provides insights into the challenges of monetizing open-source software. He highlights the difficulties in earning profits through GitHub Sponsors and contracts for developing new features, and the conflict of interest in support contracts that can hamper overall profits. Rui suggests that changing the license to a "source-available business product" or developing cloud services could be potential methods to increase profits. The show also covers topics such as compiler issues, FF4J, a framework for feature flipping, and uBlock 1.50.0, a new browser extension for blocking ads and unwanted content, as well as OpenChat, an open-source chatbot console.
