If only. I suspect that only tech enthusiasts are aware of these issues. In the meantime, non-technical people only give you weird disbelieving looks when you mention this to them, and then continue ignoring it.
It’s psychological. People can’t believe things which would make it too hard for them to stay the person they currently are. It’s almost impossible for anyone to do anything but ignore and repress such information. If you ask them later about it, they probably would deny even hearing it or having the conversation, because they wouldn’t actually remember it.
Ask anyone who tried to convince a sweeping societal change based on logical arguments. See what happened to Ignaz Semmelweis. You simply can’t convince people of hard things with logic.
What does the Purism give me? None of my existing apps work with it.
Spending zero brain cells on which computer junk to buy and getting on with my life is the most rational choice imo.
But you would probably benefit by recognizing that nothing about this is logical. There are some logical arguments why one ought to use (for instance) the Librem 5 phone as a phone and forgo the additional features present on mainstream smartphones. But you (or me) can’t be open to those logical arguments unless we’re already ready to change; i.e. when we already (irrationally) want to find a reason to do it. Then, logical arguments can be effective. But not otherwise.
