So if I have Alby Hub up and running, I don't need to pay? https://nostter.app/nevent1qqs07m7qdqhzlmpfy5xy47stm4p07la0tvm9dqldctynx8gdd0mdveq8wyjn2
The only thing that people are recommended to do is to run Alby Hub. If you do that, then you're good.
I assume you run it on your own... no you don't have to pay. Als Alby Hub is FOSS.
