As a counter-argument, i don't understand how it's even legal to sell hardware without the proper manual and schematics.

If you're worried about competition, hardware specs is what fuels competition, both for hardware manufacturers (so clients can make an informed decision about what they buy) and for software vendors (so clients have a choice).

The software competition/interop problem is very well summed up in this article: https://www.haiku-os.org/blog/mmu_man/2021-10-04_ok_lenovo_w...

Just imagine if you bought a house and the schematics were under an NDA you have no access to. You would have to contract a specific company to perform any repairs/adjustments, and said company could proclaim your house EOL any day and stop providing support for the many cracks and leaks its bad designs created in the first place. That would be a nightmare situation, don't you agree? Why is the equivalent supposed to be acceptable when it comes to phones?
