That's not what happened. Monero didn't exist. Some shady guy cloned it, to create Bitmonero. Then the shady guy starting making shady changes and broke it. The community had a meeting and tacotime decided to fork the repo using the shortened name Monero so there would be a stable source base that shady guy couldn't mess with any more (he could still push changes, and was invited to do so, but they would have to go through public review like anyone else). Later, it was decide to organize as a team and engage in further development.

Your whole narrative, while not backed by any evidence, also collapses on the basis of logic because it would make no sense for someone trying to "intentionally" exploit a crippled miner to voluntarily publicly release not one but three improvements to the miner within a short period of a few weeks. If the Monero developers wanted to exploit it they would have either released nothing or released just the first fix (which was sufficient to address the issue as far as was known at the time) and then gone and secretly mined away for months and months.
