Sounds like you feel positively about Unity and get defensive when it's attacked.
Don't get me wrong, Unity is a solid engine. I used to use it and enjoyed the experience but resent the company and their board who are still sitting pretty. Still not held to account. If it was open source, I'd probably use it, but I simply cannot trust the company to not enshittify again in the future. When they pushed these changes through, they choose to ignore their users. I could not put myself in the situation where I'd be open to getting screwed by them again. Good luck if you are fine with that risk, but you probably should understand those that put months of work into Unity and had it taken from them (myself, fortunately it was only 4 months). I'm pretty angry about it. I resent people stealing 4 months of my life.
You must be one of the few that do not believe they should diversify. Most Mozilla haters criticise the fact they are dependent on Google money and therefore not independent. I did not say it was the right thing. I said I do not believe it is, but iI could be wrong. Not sure if you aware about humility.
It is not cognitive dissidence to believe positive and negative things about a company or thing. It's call a balanced decision. It requires nuance, a key component in adult decision making. Usually children struggle with that as something is all great or all bad. Black and white thinking isn't really fit for the adult world.
You are surprised that you are supposed to back up your opinions and bring references to a discussion. This is the first time I have heard of this Steve guy. If you think it's common knowledge, you've probably been stuck too deep in the Mozilla haters echo chamber.
