Why I can’t do a single purchase and get access to all the content forever?

Whereas one-time purchase works in books, it's not the same situation in online topos. This is due to the fact that the work doesn’t end when the purchase is made but continues in the form of keeping the service running and updating. Just like you need to buy a new topo book every time you wish to get the most up-to-date information.

When you purchase the .premium subscription, all the information you get is automatically and constantly improved and updated.
