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.
I mean, you were never blocked from replacing ICs. Most people just didn’t have the capability to solder. Today, IC replacement is blocked by hardware DRM.
