There is no official report. You can estimate though. The
[https://trisquel.info/en/donate total list of donations is here].
Also for monthly income you can do some rough guesses. As Magic Banana
indicated that there are 52 associate members. The minimum contribution is 5
euros, recommended is 10, and if you can afford it 20 is generous. I
personally give 20.
So:
5 euro x 52 = 260 euros per month (minimum)
10 euro x 52 = 520 euros per month (recommended)
20 euro x 52 = 1040 euros per month (generous)
According to google minimum wage is 748.3 euros per month in Spain (where the
lead dev lives). So only if every single member is donating over 10 euros a
month (unlikely) would he even be making minimum wage. That is why quidam
had to take a job at activity central.
That is also why we push the membership program so much. If we want a
sustainable free distro in the future financial sustainability is a big part
of it.
