There is no corporate monopoly over bitcoin, and competition is good, I am not sure where you get that from, I have never said such contradictory things.
If you're in favour of competition and a free and open market, then how do you square that with the rampant protectionism going on in the community right now? Protectionism can be defined as actions or policies that restrict or restrain external competition. Core is seen as the "native" code, which some people feel has to be protected or shielded from any outside, external developers, working on their own implementations. If competition is good, you should welcome more alternative clients.
But Bitcoin development is not a free and open market, it is an individual participant in a free and open market.
That means that the project is not some kind of public institution. You have a right to choose which coin, but not to tell the coin devs what to do with their coin. Design your own coin.
And you have designed your own coin! But what's so wrong with your coin, that it can't compete with Bitcoin as a coin in it's own right? I thought you claimed it was a better coin?
