Limited number, but not necessarily controlled, and the bottleneck could be symptomatic of a change in control.

You are absolutely right however that it plays both ways - we don't actually yet know enough - but something happened.

We have evidence from other mammals and all other cases a strong Y-chromosome bottleneck is the result of harem male behaviour. If I had to bet I would say the bottleneck was driven by powerful males monopolising females, not females all choosing a small number of males.
