这两种模式长期来看存在张力，因为如果大厂自己的龙虾产品占据了市场，它们大概率倾向于使用自己的模型。这跟独立厂商今天卖API的商业模式相冲突。

Apple has also acquired a reputation for churn, and I encountered my share of that as well. I've been quite behind in updating some of my software, and so I did not have access to the SwiftUI NavigationStack and had to emulate it. The Apple developer ecosystem doesn't seem to value forward or backward compatibility — a stark contrast to the standard C example or even Apple of earlier eras.，这一点在手游中也有详细论述
When Linus reimplemented UNIX, writing the Linux kernel, the situation was somewhat more complicated, with an additional layer of indirection. He was exposed to UNIX just as a user, but, apparently, had no access to the source code of UNIX. On the other hand, he was massively exposed to the Minix source code (an implementation of UNIX, but using a microkernel), and to the book describing such implementation as well. But, in turn, when Tanenbaum wrote Minix, he did so after being massively exposed to the UNIX source code. So, SCO (during the IBM litigation) had a hard time trying to claim that Linux contained any protected expressions. Yet, when Linus used Minix as an inspiration, not only was he very familiar with something (Minix) implemented with knowledge of the UNIX code, but (more interestingly) the license of Minix was restrictive, it became open source only in 2000. Still, even in such a setup, Tanenbaum protested about the architecture (in the famous exchange), not about copyright infringement. So, we could reasonably assume Tanenbaum considered rewrites fair, even if Linus was exposed to Minix (and having himself followed a similar process when writing Minix).。关于这个话题，今日热点提供了深入分析
