That is the paranoid person's opinion.
In reality, they likely design stuff so that it is faster to assemble. Why would they care about any difficulties there may be for disassembly or service? They SELL a product and to make a bigger profit, they have to build it fast.
The same applies to the issue of headers in a classic Mopar. You think the engineers designed the cars so you'd be more likely to take the car to a dealer? No. They designed the cars to be durable, safe, fast to assemble and that is all. If any service is easy to perform, it is purely accidental.
