That's very important to point out, thanks @misdoma!
This is definitely a major obstacle for domestic development and this kingdom-esque attitude has led to Samsung and other conglomerates shooting themselves in the foot when it comes to global competition. Unfortunately, unless Samsung/SK Telekom/Hyundai/etc. proactively open up ways for startups to use their resources, I don't see many 'grassroots' entrepreneurial efforts coming about. This is a sobering reality...
