Right, I refuse to get sucked into DND beyond it any other service, we played fine before it was a thing, no need to pay to play this game. Also with all the free content available no need to buy anything apart from basics like player's handbook & DMG, though PDFs are online.

If you strip the DRM and keep a local copy of your digital content, you are no longer at the mercy of whatever services the provide it. Then you can keep a backup in case something happens to your primary copies.

I prefer to have a printed copy over a digital one for the simple reason of bookmarks. If a game is rule-heavy, I will have multiple bookmarks in parts I need to reference often. And having the bookmarks visible to me in the book does make it easier to remember which one is which section.
