We have access to lots of knowledge on paper sharing platforms, open course platforms, open-source platforms and question asking platforms and etc, and Tesla opened all its electric car patents in 2014 starting from which year XPeng and FF were founded.
I don't know why we are not afraid of the backfires of knowledge sharing or the late-mover advantage? Does a company need the often mentioned technical barrier to be competitive? In China there was a saying "师夷长技以制夷" which means literally "learn from foreigners to compete with them", then I thought those platforms are very dangerous to be utilized by enemies/competitors.
I am sorry if I asked this in the wrong place again(if so, please kindly let me know where I can post this question). I asked this question somewhere else on StackExchange and somebody suggested that I should consider comparative advantage and I learned the term here but cannot still get my head around how to answer my question using that. Any suggestions? Thanks in advance.
