On the contrary!
It has been quite successful and has met its primary goal of being the first solar sailed satellite in orbit. Hopefully in the coming year it'll met and exceed its secondary goal of proving the concept of light propulsion for such small scale systems. Once the initial research is done, there is no point in leaving it to clutter NEO, so it'll gracefully dispose of itself.
One would generally consider learning to crawl before running to be a good thing.
