Sapir-Whorf
We have always had Newspeak, and the chocolate ration has been increased again! Doubleplusgood!
Of course, the anticipated beneficial effect of changing language on thought rather depends on whether the strong Sapir-Whorf hypothesis is true. There is some debate over this.
I'm also happy that suggested other choices to replace 'blacklist' do not include the ambiguous term 'blocklist'. In general, I am in favour of using descriptive names that are clear, accurate, unambiguous, and without negative cultural baggage.
