Question

If the benefit sought from the service is perpetual and requires a fixed number of payments, then by such arrangement does ownership accrue to you after all the payments have been made? For instance, I'm set to make 4 payments for the monthly issues of a newspaper. After the 4 have been fulfilled, I'll receive all future issues free of cost. Now this newspaper also attaches to its publications all the unlawful copyright policies and corollaries that were mentioned previo u s l y i n r e g a r d t o online educational services. Since I agreed to its terms at the time of registration, am I bound to follow them once I've obtained access to its benefits (like mandating one view the newspaper exclusively on their phone and barring them from converting it into a format suitable for viewing on a computer, laptop, etc.)?
