Charging for a browser sounds crazy to me.

Crazy? I’m curious how you would characterize a cloud-based web browser that is sold using a subscription model?

I'd buy a browser if it guarantees me privacy, is fast, and does the job. I use a browser every day for multiple hours per day, $50 seems very reasonable.

Sure, but a wrapper around Electron isn't a hard thing to copy, and they've got to go from a neat tech demo to what you are describing.
