The OS alone, however, still provides a considerable privacy upgrade over a Googled system and the associated apps including Gemini, GMail, Drive and others. By default, those apps and other Google system components are incredibly invasive and remove or limit the freedom to install other programs.
I wonder how many people forking over $$$ for a degoogled phone simply go on to use it to log in to their gmail via imap with K9 mail they installed from f-droid.
