Interesting. I wonder why James didn't attempt to sell it at the very least?
36K ARR means you could have rather quickly found a buyer for 60k+ and gotten rid of the thing for a small but not in-significant payday. Also i wonder if the users are truly happy with being told they have to migrate to their own server as i'd assume they're the type who'd rather pay $4 a month instead of having to deal with the hassle.
In any case, it's quite a courageous move and seems very well-intentioned.
