Wow, when are you going to realize that you work for your users?
Do you pay their salary and have an employment contract with the developers of Lemmy? If not, they do not work for you.
And 2000€ per month is a ton of money. Most open source devs get nothing. Stop being so ungrateful and disrespectful to the community that you work for.
This is not a typical open source side project. The developers work full time on it, it's basically their job. That 2000 Euros is their monthly gross salary. Average monthly salary in France is 2340 euros net as of 2022. The developers of Lemmy are earning well below average.
