This piece has been abused in so many ways. From the annoying first few notes that we hear in band rooms, general music classes, gathering of people who know nothing about "piano" near a piano, to the corruption of it by the likes of people like Richard Clayderman.
Yet I think it is also abused by the attitude of most true "classical pianists" because of how the piece has been corrupted to become a "pop classic" or should I say "classical pop?". It's not even Beethoven's best work in the first place. We rarely hear anything past the first nine or so notes and even more rarely the two "difficult" parts that I bet most people don't know exist.
However, this piece has a special place in my heart because ever since hearing it...it has been my inspiration for learning to play at least in the beginning when I first though it must be one of the most difficult things to learn. LOL. It isn't my favorite now of course, but if this piece hasn't been overplayed, I probably would not have heard anything that would want me to play anything classical...heck the piano at all!
There must be some magic in this piece because it does get people to listen and open up to classical music a little bit. Why is this piece overplayed in the first place? I do think there would be a few less classical pianists on this planet if this piece didn't get as much attention as it does because you don't hear classical music that often imo compared to the other genres. I'm sure i'm not the only one who has been inspired by this piece in the beginning. (For me it was when I was like 6 or 7, but I didn't start lessons even though I wanted too until I was like 11.)
