Showers are closed source systems. The municipality owns, regulates, and maintains them at a cost to us. I can’t use it its not FOSS.
I can take a shower in the river , free and open source!
Your water supplier should provide you regularly (depending on local regs) with the contents of your municipal water. If you want to obtain your own rain water and make it yourself from source you certainly can.
Rain water? Seriously? God knows what’s in there. I truly build my water from source by burning pure hydrogen with pure oxygen.
Where do you get the hydrogen from though? Municipal water? Buying it online? Building a nuclear reactor and producing your own hydrogen molecules?
That’s like saying you need to fabricate your own chips.
Did you get charged by the pixel to post this or something?
GNU users when you tell them it’s impolite to publicly eat the gunk under your toenails.
