Arch does not have a monopoly for breaking stuff on updates. When I was still using Ubuntu, back in 2009 or 2010, my laptop would no longer boot after one update. After a bit of panic and some googling, it turned out that they "optimised" it for newer PCs by turning on some kernel option. There was a solution but the point is, they broke it for me. But the last straw was when an update broke my favourite DVD authoring prog (DVD Styler, IIRC) and IDE (Anjuta). My impression is that these people just do whatever "works for them", with no care whatsoever for anyone else.
