I'm a big fan of fathom and have been using it for my personal sites for about six months now- I've completely ditched Google Analytics and other providers.
When I heard that the new version wasn't going to be open source it was disappointing- both for the simple fact that I value open source, and also for how it wasn't really announced so much as heavily implied until I actually asked. Knowing that you've listened to the community and are going to open source the new version as well is a huge relief for me, and will definitely result in me promoting your product again.
I would say from a communication standpoint things could have been clearer, and I'm sure you'll work on that. From a timeline standpoint I think it would be nice if the open source and hosted versions eventually were released together, but with a full rewrite I also understand that you probably want to clean it up and make sure it's in good shape before doing so. That being said if you want some help with alpha testing the open source version I'd be happy to assist, and I'm sure others would as well.
You are the side of open-source that the world needs. We were going to keep the current repository as-is because it's written in Go, but we'll introduce a new one. Upon announcing that V2 was paid only, people were angry (understandably). We spoke with the community and the consensus was that everyone would prefer that we 'archive' V1 (Golang) and then open-source V2 moving forward. Sorry for the bad communication, it's been challenging with the move between languages!
That makes a ton of sense- you'll be able to get a lot more community support from the PHP community than the Golang one, just do to nature of size (and the fact that PHP is still very much a web language, which targets your audience well). It's been a few years since I was really involved in that community, but I still maintain a few open source projects and keep up with the language- who knows, maybe I'll be able to throw some bug fixes your way.
