Having worked at some places with what I would call "restrictive access policies" regarding internet sites and ports that can be accessed, as well as the software and configuration of computers issued to employees, I am led to the following question for companies that develop software:
If you do not trust your software developers with their own computer, how can you trust them to write the software products you sell?
If you are worried about me setting up my own printers, or installing software on my computer, or where I browse, then how can you trust the commercial software that I write for you? Sure, there are criminal penalties for the latter, but are you saying that the only way I will behave in a lawful manner is under pain of imprisonment?
