Undo/redo is totally broken on some of modern forums with too rich formatting. Most of them can easily "forget" what was in a long comment you worked on for tens of minutes after clicking a "send" button if some network issue happens (and good luck for those who relies on heavy webpages with hundrends kB of JS code). For me it is very rational to avoid some of too complicated features in software even if there weren't any bugs have been obserwed before. Especially if software is new and/or proprietary or if I'm working on something important or software has a Turing Mashine in it (Ethereum's Solidity, CSS3, macroses from MS Office etc). Another thing avoided to trust is any software "random" number generator if you have an access to coin or dice for accomplishing your task. Last but not least is not trusting to any connected device at all. So, I do not trust any software if to be honest and I hope my fear might be considered as rational.
