Or, you know, you could get an actual Scrabble board, and not have to spend a couple thousand dollars to play to play a $20 game with three friends. You can even flick the tiles at the board, if you want. For free!
Because it's not their job, or their area of expertise.
As a case in point, here's an example I dealt with a while back. One of the best developers in the company was having issues with Remote Desktop on his XP machine. He got tired of it, so he installed VNC server instead, so he could remote into it from his other workstation. And he set it up without a password, because he didn't want to be bothered to enter it every time he connected. And in order to get it to work, he disabled Windows Firewall. Oh, and this was a laptop, that he occasionally took on the road and connected to public WiFi, like in hotels, airports, and such.
Now, on the one hand, you can say he was very competent in operating his workstation. He knew how to install software. He knew how to configure said software the way he wanted. He knew how to change OS settings to make sure his software worked the way he wanted. He did all this without having to contact anyone else for support. On the other hand, he completely opened up his laptop to attack because he didn't understand security concepts and didn't see the bigger picture beyond his own needs. But he was a fantastic developer, and one of the top performers in the company.
