Comment Adobe nous a tous piégés avec le PDF — Guillaume Ayoub
Summary
This episode explores the history and business model of the PDF format, tracing its origins from Xerox PARC’s PostScript to Adobe’s strategic monopoly. Host Guillaume explains how Adobe made the specification free to read but charged for creation tools, fostering a complex ecosystem of paid licenses and ISO standards. He also details his development of WeasyPrint, an open-source library that converts HTML and CSS into PDFs, offering a free alternative to proprietary software for automated document generation.
