FOSSism · /ˈfɔːʃɪzəm/ or fawsh-iz-um · noun
A militant branch of the open source movement that delights in telling absolutely anyone that 'they are doing it wrong'. One of the fundamental social problems holding the Fediverse back. Nearly always a white dude.

@scottjenson It happens inside the FOSS/Open Source community. The fediverse thing is just tip of an iceberg.

It's Alt-tech side of the FOSS.
