You asked how much it would cost to use. The existence of these smaller services proves that the answer can be as low as free, if someone wants a thing to exist and is willing to cover the cost of hosting it (which can be as low as buying a Raspberry Pi, assuming you already have internet).
Comment on Do we know how much apps would cost if we had to replace as revenue with subscription fees?
otp@sh.itjust.works 1 week agoThe cost of those to the service provider is generally not zero though. And cost is per user, and these all have fewer users than mainstream social media and “services”.
Though Linux is an exception here, with it costing only the time of hobbyists (at least as far as I know)

Linux actually has a lot of people that get paid to work on it, especially nitty-gritty stuff like the kernel and drivers. Lots of multi-billion dollar companies rely on that stuff, so they often have some of their employees work some or even all of their working hours on FOSS.
Linus Torvalds himself is an employee of Red Hat.
