Ergo Facebook already controls the one most important thing to know about Meta.
Hard for me to believe that some little Arizona company would be able to trademark Meta "in relation to any technological use". That word has been in widespread use for quite a while.
When Google became Alphabet we didn't stop teaching English in grade school.
And with that same logic some little company in California shouldn't be able to trademark it in relation to any technological use either. Let's see what happens if another company wants to call itself Meta now.
