Thanks for posting this. I don't know how difficult it is to get an app removed from the Play Store - but hope it can be done soon.
From README - "There are plans for unpublishing the Termux app and all its plugins on Play Store soon so that new users cannot install it and for disabling the Termux apps with updates so that existing users cannot continue using outdated versions. You are encouraged to move to F-Droid or GitHub builds as soon as possible."
