Adobe Zii Patcher is an activator for most of the Creative Clouds apps. It's basically a crack which allows you to enjoy those apps for free. One of the last version was bugged but it seems to have been resolved with the latest version though. However, it's advised to use an officially activated version for this.
Nope.
Disable SIP (recovery > terminal > csrutil disable or with the opencore tool) and reboot into macOS
Download Adobe Creative Cloud: https://creativecloud.adobe.com/en/apps/download/creative-cloud
Download libfakeintel.dylib and environment.plist from the first post
Put the libfakeintel.dylib in your Application folder
Put environment.plist in your $HOME/Library/LaunchAgents (Home folder = the folder of your macOS installation)
Reboot
On Adobe Creative Cloud, download the programs you want and wait for them to finish installing
Here you go!
Basically, the environment.plist will load the libfakeintel.dylib at launch automatically.
