Not sure about this. All OSes were janky and buggy, Linux desktop up until at least late 2000s (I've been using it since ~2000), early Mac OS X, I don't even want to talk about classic Mac OS which was an abomination. Software quality and user experience was notoriously worse than it is today. This applies to everything - I've lost a ton of work to bugs in ZBrush, Maya, Word, FL Studio, backup software, and more.
