I'm sorry but this is just nonsense. LAMP is called that because it was a very standardized thing. Pop in a Debian CD and select a ready made profile for it. There were even ready made installers for Windows and Mac if you weren't on an Internet native operating system.
A lot more people got by using custom bash scripts, but cfengine exited in the 90s. It's still not honest to say things were more manual. Take a look at /r/homelab or somewhere selfhosters hang out today and look at the Compose or self hosted K8s stacks people set up today. That's orders of magnitude more manual work than just popping in a CD and selecting LAMP.
Yes, those are not the same thing. Yes, a self hosted stack today consists of so much more than running PHP in a web server. But for self hosters, the amount of work required has objectively gone through the roof. That's a problem if your goal is data sovereignty.
