This is exactly Termux's point, to subvert Android into linux cheaply. Same for MinGW or MSYS2. I want to invest as few as possible on Andriod or Windows, while still able to use them in the way that I prefer.
Mine is that the Unix environment is a preferred one, particularly on a device which is nominally a Unix derivative (Linux -> Android) but which fails to deliver in its stock incarnation.
Termux doesn't solve that problem entirely, but it does remarkably well given the underlying limitations.
As computer nerd I favour diversity just like I had the pleasure to enjoy during the 8 and 16 bit home computing days.
Vertical integration of computers with a soul, full stack experience.
