Giving it away for free didn't help, but "making money" was never really a goal as such. I think "being free" is important if you want to be a viable alternative for Google Analytics. €9/month is nothing for a business, but who is paying that for a blog or hobby site (or even some small businesses)?
I already decided a few years ago that "covers hosting" is good enough. It's just that circumstances conspired to put in this rather uncomfortable position.
