No -- for all the machinations that M/W wants to put out, "data" is the plural of "datum." M/W has been undermining the english language for quite some time, including such linguistic abortions as "prioritize."
Just because a handful of idiots use something wrong conistently and pervesively that doesn't bestow propriety.
Either something has meaning or it doesn't. Please don't feed me that "English is an evolving language" claptrap. English is a series of defined syntax and usage. Words OTOH either mean something or they don't.
Just yesterday I saw, IN PRINT, the term "mediums." I suppose you support this as well?
That would be two or more fortune-tellers, right? Or would you call them "media?" Come on, this is 21st century America. There's no need to enforce old, outmoded rules. Everyone ought to be able to make up their own rules of language and everything else. What are you, some kind of word Fascist? :)
