The more electronics in a product, the easier it is to build in Engineered Obsolescence.

One good thing about traditional ICE engines is that they were relatively simple. If something stops working, it can be bypassed.

Modern ICE and EVs use CANBus and FSB/DAS, which means that the manufacturer has infinitely more control over the vehicle than a vehicle with disparate components that are individually powered and controlled.

This is more of an “old vehicle vs new vehicle” argument, and as EVs mature, the aftermarket replacement parts (such as the OpenInverter project) will be more accessible.

The Automotive industry is seeing the EV boom as an opportunity to fight Right To Repair with the argument that a giant Lithium bomb under each vehicle is too dangerous for lay-mechanics to work on.
