I am writing this on Tusky, which is free software that someone had to write. It is running on an older Android phone, which someone had to assemble from components that other people had to make from raw materials that still other people had to produce.
You are reading this because it was transmitted via a sophisticated international communications system which someone had to design and someone else had to make from raw materials that someone else had to produce.
The electricity also had to be produced by someone, using machinery made by someone else.
Happy May Day, y'all. The world is nothing without our labour. Our masters know this; we should too.
