Apologies if this is explained in the article (sorry, as a Linux user I don’t care enough about this story to actually read the article), but… how is a filter that avoid taking screenshots of sensitive info supposed to work? I mean, what kind of divination algorithm can detect something is sensitive without looking at it first?

Agreed: now that I’m looking at the whole thing, this looks like a story where the FOSS community left much to be desired.

I know nothing about Wikipedia drama, but the term “logical fallacy” usually indicates a reasoning pattern and does not apply to specific arguments, regardless of how fallacious they may happen be. See https://en.wikipedia.org/wiki/List_of_fallacies
