You've done a lot of work, so don't think its worthless just because someone else jumped in. But you need to strategize and think about all the ways this will affect you. What was your monetization strategy in the first place? You may need to change it to account for the new development. Maybe you'll license your code instead, or come up with something new. But don't just give up without at least thinking long and hard about what your business can do. You should also research what Google, Yahoo and Adobe (hey, where's MSFT?) have ACTUALLY done, not just said they will do. You may have an opportunity there as well.
