Vendors often pitch customization as a feature of their software:

In my experience, software customization is as much a danger as a benefit. I am reminded of the Tar-Baby parable:

The Tar-Baby didn't say a thing.

"What is the matter with you then? Are you deaf?" says Brer Rabbit, says he. "Cause if you are, I can holler louder," says he.

The Tar-Baby stayed still.

"You're stuck-up, that's what's wrong with you. You think you're too good to talk to me," says Brer Rabbit, says he. "And I'm going to cure you, that's what I'm going to do," says he.

Tar-Baby didn't say a word.

"I'm going to teach you how to talk to respectable folks if it's my last act," says Brer Rabbit, says he. "If you don't take off that hat and say howdy, I'm going to bust you wide open," says he.

Tar-Baby stayed still.

Brer Rabbit kept on asking her why she wouldn't talk and the Tar-Baby kept on saying nothing until Brer Rabbit finally drew back his fist, he did, and blip--he hit the Tar-Baby on the jaw. But his fist stuck and he couldn't pull it loose. The tar held him. But Tar-Baby, she stayed still.

"If you don't let me loose, I'm going to hit you again," says Brer Rabbit, says he, and with that he drew back his other fist and blap--he hit the Tar-Baby with the other hand and that one stuck fast too.

Tar-Baby she stayed still.

"Turn me loose, before I kick the natural stuffing out of you," says Brer Rabbit, says he, but the Tar-Baby just sat there.

She just held on and then Brer Rabbit jumped her with both his feet. Then Brer Rabbit yelled out that if that Tar-Baby didn't turn him loose, he was going to butt her crank-sided. Then he butted her and his head got stuck.

Brer Fox walked out from behind the bushes and strolled over to Brer Rabbit, looking as innocent as a mockingbird. "Well, I expect I got you this time, Brer Rabbit," says he. "Maybe I don't, but I expect I do. You've been around here sassing after me a mighty long time, but now it's the end. And then you're always getting into something that's none of your business," says Brer Fox, says he. "Who asked you to come and strike up a conversation with this Tar-Baby? And who stuck you up the way you are? Nobody in the round world. You just jammed yourself into that Tar-Baby without waiting for an invitation," says Brer Fox, says he.
