I find this argument difficult as this is kind of how China operates. This free sharing of IP was claimed to enable untold amounts of innovation. However what I actually see for the most part is a market flooded by shitty clones of original IP.

For example, take this dumb phone[1]. It is powered by a Mediatek processor whose IP is freely shared. The innovation that resulted is not something better like an iPhone. Instead 1000s of different shells or an additional button here or there.

I guess this scenario might be a bit different since we are talking about software...but i'm not so sure.
