It’s also worth noting that people with undisclosed skeletons in their closet are blackmailable. So even if they represented your interests in the past that all ends once someone puts them on a leash.

That’s only cheap if you don’t consider how long it will survive and the replacement/repair cost. A slab phone with no moving parts will last much longer than a foldable making the $/year cost much lower.
