DeletedUser201 GrapheneOS users are welcome to install Google apps on their phones if they wish. Considering they're here and use GrapheneOS, I'm sure they know full well Google's reputation for collecting data. Community members should be able to talk about using Google apps here without having to worry about people being rude or judgmental.
As I recently said in another post, this isn't a "Google bad" forum. On GrapheneOS, Google apps aren't privileged and are subject to the same restrictions as regular apps, so it does make sense that some people will want to use Google apps on GrapheneOS because they do benefit from privacy and security improvements in GrapheneOS.
