To all,
I don't and haven't "bullied" or "forced" my parents into the use of any software whether that be an application or operating system, please don't get this confused when I use the term 'argument'.
I used an example of the recent retailer hacks in here the UK as an example where my parents were receptive to the use of a password manager, after explaining the downfalls of repeated passwords. They already use Signal for family and friends chats as oppose to WhatsApp and happy with the app.
My parents are coming to retirement age here in UK and are generally good with technology, but need a hand now and again. Hence why I am helping them with setting up their new devices, I am opposed to installing an OS against their wishes as some have suggested (although I appreciate the advice).
I have explained what I feel are some of the benefits of GOS to my parents. They (like many) feel that they have nothing to hide. This is why I am seeking advice on how to fully explain the software to them in a constructive fashion that's easy for them to understand and value.
Thanks to all who have replied to my post thus far.
