At this point, I don’t mind paying something every year to keep development going (there’s always something that needs to be fixed on new Android versions) and so the author doesn’t feel the need to sell it, but monthly subscriptions… I don’t know.

I think I paid the equivalent to $4 a few years ago for Nova. I’ve been using it for 10 or so years. I wouldn’t mind paying $4 per year just to avoid this sad outcome.
