"Patching is Hard", yes but the brick wall of a massive cyberattack is harder. It's not an excuse, not patching is a bet, its people saying "This is difficult so I'm going to skip it, in exchange for increasing the chance of a huge amount of difficulty in the future"

I bet all the hospitals are really glad their managers/IT staff avoided the difficulty and small uptime impact of patching now ...

Hopefully budgets will be allocated in the NHS at least to prevent future incidents like this.
