The latter. If for whatever reason you cannot obtain the firmware files legally, then you will simply have to obtain them illegally. Not to worry as there are outlets that provide dumps of Nintendo Switch firmware files; its just a matter of tracking them down.Yeah I get that but where do I get the update-data from if not from sysMMC? Is it downloadable in the same way you can download iOS and PS3/4/5 firmware files on PC somehow?
