Beyond legality, there are practical and ethical costs. First, quality and safety. Most free PDFs circulating are poorly OCR-scanned, missing audio (critical for pronunciation), or laced with malware. The learner gains a broken tool, not a path to mastery. Second, the psychological cost: when we obtain something for nothing, we often undervalue it. Studies on digital piracy suggest that “free” materials are less likely to be used consistently. The act of paying, even a small amount, creates commitment. Third, there is the community cost. Publishers like Assimil have invested in companion apps, forums, and teacher networks. By bypassing payment, the learner excludes themselves from that ecosystem. Create your own advanced course:

Believe it or not, previous owners have uploaded the audio tracks of Perfectionnement Anglais to Spotify, SoundCloud, and YouTube as "playlists." While the PDF is illegal to distribute, you can legally listen to the audio in the public domain (depending on uploader rights). Buy a $5 used book and use the free audio online.
