They are not really identical and forked from the same base project, they may have similar features. Acode is foss,built using cordova and JS tech,has its own plugin system. Squircle is also foss and built using kotlin. Vscode for android is just code server inside web view wrapper or browser and embedded git. I can't speak for the other ones as they are proprietary.

I understand that VSCode is different, hence the "though" part of my sentence.

The remaining examples are all almost identical, though.
