Sure, but that has always been the case. I would buy the argument if it was a change by a specific S&P 500 ETF, but since it's the index itself it doesn't seem like anything is changing.
It's irrelevant that "hey, I'm just following the index", since the index is inheriting an active manager's judgment. The more such judgment is exerted, the more the index becomes someone's active management. At some point, it is not really an index fund (as properly understood), but an actively managed fund (albeit low-cost).
The OP's concern, then, was that making this kind of decision about "man, these multi-share stocks are too nutty" is getting close to looking like active management rather than some robotic, mindless tracking of some mostly-objective market measure.
