One probably non-obvious thing is that the $100/yr ish unlimited storage tier includes everything you do as a user including shared libraries.
So if you have a group of people working together in a group library, one shared library subscription covers all of them. It doesn't take many people to make this worthwhile.
And as you say, it's a good way to support a great project. I do it even when I'm not really using the software.

I'll drop a one-time donation of $10 or $18 or something largely independent of my use - or even if I don't use it at all. I don't treat it as a purchase, though I can understand that others do.
