No surprises here. Just like the lockdown on iPhone screen and part replacements, Macbooks suffer from the same Apple’s anti-repair and anti-consumer bullshit. Battery glued, ssd soldered in and can’t even swap parts with other official parts. 6000$ laptop and you don’t even own it.
Lenovo did not run ThinkPad to the ground. User repairability has become a lot more accessible to the average user since, and unlike greedy IBM, Lenovo prices them at various tiers. The only thing that has become less accessible is the battery, which is behind a few screws and a back cover now, to make the laptops thinner and lighter.
I have seen plenty ThinkPads being given to employees in corporate India, and they just work, unlike Dells and HPs, and are not astronomically costly to to buy and repair like MacBooks.
