But the question here is if it should be illegal for manufacturers to make the modify a product.
The difference is between a locked down boot loader and one that is just a standard boot loader.

In general if there are no legal recourses to go after people who modify their devices, then it makes it more appealing for manufacturers to allow a supported opt-out method because that reduces the incentives to compromise their products with out-of-band methods.
So I'd prefer to take an indirect route of empowering customers rather than requiring manufacturers to do additional work to free up their products.
