I think in a discussion about the effect of immigration on the current state of an area, in this case Silicon Valley, you can totally reference its history if you are making a claim about a chain of events. If instead, you skip over 50 years of history which includes multiple generations of how the industry worked and multiple generations of immigration policy, to start talking about

> The highly selective immigration policy that prevailed from 1924-1965 is likely a key reason why so many Silicon Valley companies were founded by immigrants

then you are making a narrative that has nothing to do with the point, and I am unwilling to accept your framing.
