If you don't do it simultaneously, you're going to hear by rumor rather than by official email, which is IMHO worse.
If you do it simultaneously, everyone will know something is up, because there's never simultaneous global meetings.
Is it polite to let people stew for hours, or days, as virtual meetings spread across the company to convey the news in person? It is polite to schedule those meetings all at once with the implications clear - how is that any different than just confirming it an email? Is that better or worse than scheduling such calls with short notice, so that every employee must wonder for days (maybe weeks, depending on staffing and leverage model) whether they still have a job, when that information could have been communicated immediately to allow for immediate preparations?
You and I as senior managers might both apply the golden rule in this situation, but that could lead to different decisions.
Oracle as a company are cowardly and rude and the practicalities are simply an excuse. There's clearly one "better way" which is to put a name at the end of the email, for perhaps Larry himself to take responsibility as he should.
If anything the practicalities show how arbitrary the decision was. Checking the Oracle subreddit we got people with "exceeds expectations" as their average still getting culled. It would appear how they decided upon the cuts reflects on how they have performed them. With all the sophistication of a child in a candy shop trying to buy more candy than their piggy bank can afford and then just dropping the excess on the floor, walking away and trying to forget that it ever happened.
I am communicating my own sincerely held belief on general practices with large-scale layoffs, and my sincere disagreement with the black-and-white declarative than a mass email is definitely worse than individual conversations. Reasonable people can disagree.
I am not evaluating the full list of circumstances in this specific situation as I wouldn't be able to even if I were interested in doing so. If we were taking wagers, I'd wager my opinion of the Ellisons is at least as negative as yours independent of anything to do with this story.

Completely agree with that, though ultimately it should be many names, not just one.
