Yea, that really depends on how you use it. In my case, my subscriptions are only worth it when I am being active. When I can barely touch a service and it just sits there then it is pretty much a waste of money. The gimmicky part of it is that these month to the month charges can pile up unintentionally and as such, it could be easy to continue paying up on things we do not need. I aim to check mine about every couple of months or so and cancel things that I am not using. The good part is that we do not have to wait now to do something with alternatives, and it is quite easy to switch or to wait.
I think subscribing only if you truly need it is the right option, because that's what I've experienced. I tried subscribing yesterday, but I didn't really need it because I only used it occasionally. Then, with the mounting bill, I realized I needed it and chose to cancel it because I didn't really need it.
One thing I still choose to subscribe to is Wi-Fi, because it's something I really need, primarily for work, and it has other positive aspects as well.
