Exactly; the comment section on sites like often reads like a conspiracy foil hat orgy. Windows 10 works great. I applied the update and kept all my files and haven't experienced any problem. Still, there seems to be a hiccup or we wouldn't have these reports. A hiccup that is easily reversed by numerous methods including free restoration, free recovery, or restoring your own backup. It boggles me there are people still out there that run their system with no backup. Yes, Microsoft should have caught this in the beta/preview build stages. Unfortunately mostly only competent, capable users take part in that program not the ordinary commoner that sometimes uses less than sanitary system organization so things like this don't expose.
Until some meaningful alternative comes along it is best to set aside the tissues and screaming pillows. It is ok to voice level-headed reasonable comments with a sense of perspective.
