Does BSD have a true microkernel architecture? Do all drivers run isolated in user mode, making it extremely robust? Does it fit in a tiny footprint? No? Then it can't work as well in Minix's target market.
Of course, the real reason BSD isn't the standard now instead of Linux is people like you falsely claiming theft. The AT&T lawsuit held up acceptance of BSD just long enough for Linux to take hold. Linux was already popular by the time BSD was in the clear.
And Linus has been quoted as saying if he knew about the x86 BSD project before he started Linux he would have went with that...
No, the reason Linux is popular is the radical leftists love the communistic "copyleft" aspect of the GPL license, and socialists the world over are rallying behind it. Threats of something being illegal don't curb the desire of those who want something for free in the least, just as we're seeing now.
