Why are the installation instructions aimed towards Linux?
Sorry if it sounds a dumb question but I always thought using the official playstore that comes pre-installed is the safest so everything related to F-Droid is new to me.
Did anyone had apprehension on installing F-Droid when you had bare to none knowledge how it works? I like to be cautious and on the page it has a Instructions to verify the download page and it only tells how to check from Linux but not from Android, what am I missing here?
Asking "is it safe to use" is pointless. No one can say an app is "safe", just that they've never seen an issue.
I'd argue Termux isn't safe, because if you're rooted you can break the OS. And I use Termux every day.
"Safe" is determined by your use-case and what you do. I'd even argue there's no such thing as "safe", just a risk level which you are comfortable with.
