Lol, I run multiple FOSS services online, two of which have thousands of MAUs. I consider myself lucky to be even covering the hardware costs at this point. I would love to even make an extra 500 Eur per month for myself given the amount of time I spend doing sysadmin, automation, PR, development and just being an active part of the communities.

We really need to change in what people consider valuable and how little actually is needed to help. Like literally, all you need to do is spare 1$ per month on your social media that is your primary home. If every user did that, all those service providers would have so much support.
