I did something similar too. This is actually very bad for Apple - because I've now had the same Macbook Pro for 5.25 years, and it's remaining serviceable thanks to RAM upgrades and a modern high-capacity SSD. I'm sure it will end up lasting 5.5 years and it seems like there's a fair chance it will (Apple software support and wobbly ports permitting...) last for 6. But if they'd forced me to pay for all the upgrades up front, I'd probably still have bought the same spec (the 8GB RAM option was eye-wateringly expensive at the time, and the SSDs were comically pricey) - and then I'd have had to buy a whole new one after 2 years. Which probably wouldn't have had an SSD, because they were still expensive back then. So I'd probably be buying another one round about now, if not before, and Apple would have had 3 purchases out of me rather than just one.
