> The rules are in place for a reason, why does it matter what the percentage is? They're not profitable. When they prove they're worth the dollars, they can be included, per the rules.

I'm sure you know this, but the rules have been changed many times over the years. Now that companies IPO much later with huge market caps, I suspect we'll see more rule changes over time. The S&P 500 is fairly conservative, so they held tight this time. If these companies are still 1T+ 12 months from now, there will be a very strong argument that the market has decided these companies are important regardless of current profitability, and the S&P will likely have to revisit.
