Didn't tell me there wasn't a freebie mode until after I'd gone through a lengthy process of giving it info to choose which program I'd supposedly be on. This is predatory app style, aka a Dark Pattern (uses Sunk Cost fallacy, and wastes the time of anyone who's not going to subscribe). I'm actually surprised that it let me skip giving them my email before telling me that it's exclusively a paid subscription. I'd be happy with a few dozen older/classical books to read, but apparently not.
