I mean... really? For the same reason that instrumentalists and vocalists have been constantly fiddling with the original printed note since the dawn of music by adding vibrato, playing in octaves, etc. Because they want to show off. I'm neither condoning nor condemning the practice of embellishment, but it should be obvious why people do it.
