> YC funds competitors all the time and would never turn down an innovator for anti-competitive reasons
While I know your intentions weren't bad, it feels disingenuous to speak so confidently about the behavior of hundreds(?) of investors/employees, regardless of the take. Also getting a seed check from YC doesn't really disprove any of this. The forces of the business immune system he's describing probably wouldn't kick in until later anyway.
To be clear I don't think any of this is abnormal behavior (or reprehensible). Regardless I stand by my bet: the successor to Airbnb & Stripe probably wont be YC backed.
