Is "be" really required after "may" in this sentence? [closed]

I read a sentence in "The Hindu" which was:

Age maybe has slowed down MT Vasudevan Nair but his creativity remains undiminished.

I think it is an egregious error to use may be this style. Shouldn't there be just "may" before "slowed down"?

Maybe is fine.

It functions as an adverb meaning "possibly" and modifies the verb phrase "has slowed down." I can't speak for Indian English, but in American English "maybe" immediately preceding a verb would hit a lower register than "maybe" at the head of a clause. (Compare: "Maybe age has slowed down ...")

Here are two other examples found through the Corpus of Contemporary American English out of several dozen. "Maybe" preceding a verb crops up in more speech than writing (most results involve live news programs):

("Rebel on the Edge," Time, 1/23/2006.) He is the world's best ski racer, but whatever the result, he laughs it off and maybe has a beer afterward.

("United Shades of America: Off the Grid," CNN, 5/22/2016.) And so what would you say to somebody whose sitting at home right now, who maybe has just seen this for the first time and is going huh?
