According to author Matt Hartley, the idea of TC is quite reasonable; offering a locked-down environment offers several advantages to system administrators with possibly troublesome users. 'With the absence of proprietary code in the mix users will find themselves more inclined to trust their own administrators to make the best choices ... And so long as any controlled environment is left with checks and balances [like] the option for withdrawal should a school or business wish to opt out, then more power to those who want a closed off TC in an open source world." LWN.net has an older but slightly more balanced look at the TC approach.
