DeletedUser237 Compared to a phone running GOS, I'd agree, I trust GOS more than other desktop OS.
But desktops vary wildly, if you want pure security, Windows or ChromeOS (note, pure security, not privacy), ChromeOS is the easiest for security, especially with APP, Windows can be configured to be just as hard to breach as ChromeOS, but it requires an enterprise license and systems admin knowledge.
For privacy, I'd trust something like Fedora, even Ubuntu, yes it sends telemetry, but its not as bad as the other big 2.
I try keep sensitive stuff to a GOS device if I can (banking being a prime example).
