Not every privacy lovers use GreaphenOS and many have stock android. Stock android has many useless bloatware from Google and the vendor. Every bloatware may have security and privacy issue. So It is recommended to remove all bloatware that is not used. The problem is, many bloatwares cannot be uninstalled/disabled from android. So recommending bloatware removing software in website would be great.
I find Universal android debloater so useful. Because:
It doesn’t need android device to be rooted
It is open source
It can be run on all desktop operating systems (linux, windows, android) and doesn’t need administrator access
It categorized risk of removing bloatwares (recommended, advanced, expert, and unsafe). So even beginner users can remove bloatwares in recommended section without risk
It gives easy GUI access and a community curated list of which apps is safe/recommended to remove. I don’t see PG listing the apps one by one as even the recommended list on a single samsung phone is at least 50 apps if not nearing 100
And again it would still be better to just use a custom rom
