It’s not secure if the user installing the software doesn’t understand network security at all (which you don’t, and admitted) you seem to think security is an issue with your personal data being harvested whereas I’m talking about actual security like threat actors hacking into your storage arrays to encrypt or steal information.
But it’s fine, I’ll take my ten years doing security analysis and network engineering and go. Clearly you’re an IT expert since you can install Linux.
This place is full of people like you, who think they understand the way things work but are focused on big scawy Microsoft meanwhile installing god knows fucking what from god knows fucking where. I use Linux and love it, but script kiddies like you are the bain of actual IT professionals existence.
