Same, I even remember paying for LastPass for a bit. It was more that I wanted to support a service I liked (same reason I pay for other services). Though I find BW's paid model a bit surprising. I know it is only $10/yr, but the only real value here is 1GB storage and yubi/fido keys. I don't have yubi keys (they seem cool but also a pain in the ass) and 1GB seems rather small.
Looking at Google, Dropbox, and Apple, storage pricings range from 4GB/$ (Apple) to 20GB/$ (Google's 5+TB plans). I'm willing to bet that offering 5GB would make it more worthwhile and a very small fraction of your users would actually use it. What are you going to store? Your passport photo and driver's license? I wonder if there would be a psychological effect here because it is really hard to tell if 1GB is enough or not. At least your average person has no idea.
