No one wanted to change anything for racial sensitivity reasons. If you read the whole story you'll see that an IT professional just mentioned that in his opinion a blocklist would be a more technically correct term. Now I'm not one to judge if he's right or wrong because I don't know. But it had nothing to do with race just someone being pedantic and trying to look clever!
What I saw in the articles I read was that they did suggest blocklist was an appropriate word that was commonly used in IT, but that it was also more appropriate because of sensitivity reasons

The ban emerged in an e-mail to Yard IT staff from security services chief Brian Douglas. He wrote: "IB [Information Board] are uncomfortable with the use of the term whitelist [and I presume blacklist]. I am sure we can appreciate the sensitivity around the use of such terminology today so please ensure it is no longer used."
Sensitivity about what? What is he referring to?
And about the appropriateness --
He said: "This is not a change in policy. It is a change in internal ICT terminology which reflects a more appropriate use of language in a professional, policing environment."
What does the technical accuracy of the term have to do with a policing environment?
