You are claiming these words are "not inclusive" at first place, which is purely a matter of ideology, not semantics. Words have different meaning in different contexts. If you can't understand that, off course you will find everything "offensive".
Starting with the word "inclusive" itself which basically is newspeak at that point. You are right, language changes over time, and it's being manipulated by people like you to steer controversy and division, to deem this or that racist, sexist because you willfully ignore context for pure political goals. There is nothing confusing about "blacklist" or "whitelist". anybody can look up these words in a dictionary, if your "engineers" are incapable of doing that, maybe you should hire better ones. "allowlist" on the other hand is a useless neologism only driven by the need to effectively control the language to force your ideology on others, under threat of being deemed "not inclusive".
This is a political stunt, nothing more, you are asserting control over others, in the name of "inclusiveness" which is rather exclusive as a matter of fact...
