Well put, that’s the most commonly experienced anti-feature introduced, another less common one where they have been less and less lenient over the years is geolocation restrictions: people in the past could register with other countries (cheaper) pricing, today most legitimate customers cannot access their content even when traveling for a few days, or they risk getting blocked. Similarly to the region-codes on dvds and blurays, I can’t imagine it really helps sales, but it siloes consumers into country blocks and monopolies tend to like that.
