None of them has details about the reasons, which led Linux Kernel developers to reject STREAMS. STREAMS was only vaguely described as poorly-designed and resource-consuming.
There were two competing implemtations of TCP/IP. UCB created sockets, which is sort of in the public domain. AT&T (I think they subcontracted BBN to actually do it) created streams.
My guess is that streams is based on AT&T patents and was never reverse engineered.
So UNIX systems based on SYS V had streams, while UNIX systems based on BSD had sockets. SYS V Release 3.2 which was the first combined release (AT&T Kernel, both SYS V and BSD user land) had both.
I've never looked but AFAIK, MacOS which is the latest "real" UNIX has sockets but not streams.
