@lispi314 @mikoto @wolf480pl imo repair and upgradability are separate concerns even if they overlap to some extent

the latter simply shouldn't be necessary, after all artificial market segmentation for electronics is a scam to charge you more for hardware that barely costs more to produce, there is no reason to sell crippled CPUs and machines with less than the maximum supported amount of memory

for repair, I don't really see anything wrong with leaving that up to specialists
there is a real engineering trade-off here, they're not just deliberately making it harder to repair even if it happens to be convenient for them
similar situation for combustion engines with cylinder coatings replacing cast iron sleeves in aluminium blocks, which makes them prohibitively expensive to rebuild, but unlocks performance *and* makes them significantly more durable!

the sad reality is that capitalism will not do the right thing here anyway, and in most cases perfectly repairable machines end up in the landfill/junkyard regardless of user serviceability for a whole host of reasons, including user miseducation and obsolescence, or insurance writing off vehicles way too liberally
