I would note that some ESG ETFs in which I hold shares (i.e. where the portfolio make-up and allocations are informed, to some degree, by Environmental, Social, and Governance characteristics of the eligible corporations - basically a somewhat more ethical version of an S&P500 index fund) exclude Facebook while retaining stakes in Google and other major tech companies. (Can't recall with confidence but I think it's a BlackRock iShares fund)
