The #ZorinOS website says:
“Why #ZorinOSLite will be sunset?
Thanks to recent optimisations to the standard desktop environment, the non-Lite editions of #Zorin OS (Core, Pro, and Education) are able to provide a fast and resource-efficient computing experience on older computers. It’s now possible to run the non-Lite editions of Zorin OS on computers with as little as 2 GB of RAM and on machines as old as 15 years, with higher performance than the Lite edition in some tasks”.

Which is not true.
Zorin OS Lite will be sunset because it’s not light enough for most people who give it a try. Period.
There’s plenty of lighter distributions that work better on old computers than Zorin OS Lite, like Puppy Linux, Tiny Core Linux, Linux Mint, SliTaz, Damn Small Linux, Loc-OS, Lubuntu, Xubuntu, Fedora LXDE, just to name some.
