Why is it fully automated, let alone connected to the internet with 0 security measures, in the first place?
It's fully automated because industrial scale water treatment isn't something you can reasonably do by hand. Even if setting up the system for remote access is necessary, I'd at least use the network firewall to block untrustworthy IP addresses (which still isn't foolproof, but at least forces an attacker to VPN into the US before even a valid password is accepted).
Should have required user input especially when levels are going to change outside of usual parameters.
The system shouldn't be able to just dump unsafe amounts of lye in without human oversight. It doesn't cost that much to hire an operator to essentially just watch the system
But the unprotected remote access is the main problem anyways
When the problem can be solved by Homer Simpson (wasn't that basically his job at the power plant? Watch for flashy lights and approve/click them?), then you have no excuse to not solve the problem that way until a better solution can be found.
Here's an English article on the same incident

Exactly
