I've been changing spark plugs for over 30 years and on vehicles with aluminum heads and I've never had issues taking plugs out that didn't have anti-seize on them except in this one case. She got the engine hot one time some years back and that is probably why I had an issue.Assuming the O2 sensors weren't screwed into aluminum, so not a correct comparison.
If people want to use anti-seize, have at it. I don't use it and don't plan on it.
