I didn’t understand this for a long time myself. And I can’t rightly remember when I first learned about this sort of thing. But once I did, information just seemed to flow to me from multiple directions. Maybe look up classic tactics around sales and marketing, then deceptive, yet typical, psychological sales and marketing practices. There’s a book on credit cards I enjoyed years ago “How to Take Advantage of the People Who Are Trying to Take Advantage of You: 50 Ways to Capitalize on the System” by JSB Morse (Though long story short, avoid debt and credit cards). One video on YouTube turned me off of buying ink cartridges once I found out what they truly cost versus the exorbitant amount they sell them for. Capital rip offs.
Right, so what is the relevance of this in the context of owning your own media versus being milked for money by corporations and having what you paid for removed at their whim? You’d have to be familiar with common usage of media players up to today to give a knowledgeable comparison on what was and is normal or impractical in that area, let alone the meaning of digital, which you don’t appear to be. My point that owning is better than allowing corporate exploitation for convenience sake still stands.
