Again, go back and read the links, because it is obvious that you have not. Yes 568A follows USOC standards, but that is only due to it is used for T-1 & Computer Networking, which T-1 is. How much more do I have to argue that you are wanting to believe what you want, but I am going by what I have linked, and what I was trained to do over 20 years ago, when I went through school for doing telephone work. And as I also mentioned it is up to people to use what they want in their homes as their standard, no one is going to go in and state that they should be using one over the other.
To clear some more confusion why the two standards are used:
"There are two accepted standards for 8-wire data network jacks (commonly and incorrectly called "RJ-45.")
ANSI/TIA/EIA-568-B "Commercial Building Telecommunications Cabling Standard" lists both wiring configurations. T568B is the most prevalent for commercial installations, and was used by AT&T for the original Merlin phone systems. To help you remember, associate "B" with "Bell."
ANSI/TIA/EIA-570-B "Residential Telecommunications Cabling Standards" recommends T568A
If the installation is residential, choose T568A unless other conditions apply (see below). The two inner pairs of 568A are wired the same as a two-line phone jack.
If there is pre-existing voice/data wiring (remodel, moves, adds, changes), duplicate this wiring scheme on any new connection.
If project specifications are available, use the specified wiring configuration.
If components used within the project are internally wired for either T568A or T568B, use that wiring scheme.
Make sure both ends of a cable are wired the same way."
only reason you have a lot using 568B, is because it became the standard in 2002, but was actually used prior to even 568A was the standard in 1995, as stated before, due to 568B follows the ATT258A. As for 568C, which is the next gen, it will change things again. Only thing to remember is use the same wiring method through out the cabling, but most like myself as I have stated twice, use 568A for ethernet, 568B for telephone, just so you can distinguish between the two which is which, and makes things easier in the long run.
But really it is up to the person doing the termination in what they choose, and no one has to make that person use one method over the other, it is all personal choice what they use. As for 568C wiring standard being the next gen, it is still being ratified as to how it will be done in the long run. http://www.cablinginstall.com/articles/print/volume-16/issue-9/features/design/568-c0-the-next-generation-of-cabling-standards.html
