Eliminate annoying warning on bash shell login

I prefer a bash shell. How can I get rid of the annoying notification (below) each time I log in? It seems to be coded into the /bin/bash binary.

The default interactive shell is now zsh.

To update your account to use zsh, please run `chsh -s /bin/zsh`.

To silence this warning, you can add this command to ~/.bash_profile or ~/.profile:

export BASH_SILENCE_DEPRECATION_WARNING=1

Thank you! While it's fine to have a new default, please don't eliminate the bash shell from MacOS. It is a popular shell and it is the longtime default in Linux. Those of us who go back and forth, and/or who have been using bash for decades, appreciate having it available.

I do not see this happening.

You can see all Shells available from the Terminal.app copy and paste:

cat /etc/shells

None of the shells were eliminated, but bash is now licensed under GPLv3, so Apple will not install any current version with the OS as the license is incompatible with any hardware company such as Apple.

If you need to use bash, you might want to consider installing a current version.

Of course, Apple has not eliminated Bash 3.2.57 (yet), but on Linux, Bash is now up to version 5.0 and has left Apple's ancient, syntax limited version in the dust. Unless of course, you brew install current bash in /usr/local/bin, or use another package manager to do the same, and then shift your PATH to pick up that current Bash first.
