When I engaged on the substance of the argument you said "you're too focused on product here, which is not strategy", which isn't a statement that can be engaged with. It's an unusual claim that you didn't justify. I've repeatedly given examples of what I believe to be more coherent strategies, and you've functionally ignored them (and yes replying with "you're not thinking about this with the right mindset" is not engaging)
To be clear, even if we assume Youtube's rise was anticompetitive, your argument relies on that being the explicit strategy, which well, there's decent documentation to believe it wasn't. Assuming that because a bad thing happened, everyone involved is evil, is weird, and requires you to jump through weird hoops to justify.
