Just use F-Droid or download from GitHub then. The power of Android is that you're not in a walled Google Garden and you are in control and can sideload whatever you want from wherever you want.

that's what i'm doing now, but it's probably only about 3 years away that google disables the api level that termux depends on; then you'll have to install lineageos or something in order to be able to use termux
