why? - they are offering a toolkit for creating new cryptonotes, why should that be a threat? I think even mid and longterm this is good for monero.
I agree. Among the many shitcoins that will arise from this, there might also be a few good ideas, some of which might even be integrated
into Monero. And then, if the same feature becomes available in an established coin like Monero, many will prefer that over the new coin (hopefully).
