> The point of the article is that tech, specifically the big names we all know, account for the vast majority of the indexes gain this year. They are asking if you should go against the index weighting and do your own weighting so you aren't so heavy on tech, but again, that goes against the ethos of passive investing.

I don’t think this is quite right. The article is observing that weighted indexing goes against the ethos of pure passive investing, since it overweights the bigger companies and exposes you too more risk in the event that one of the highly-weighted stocks takes a big hit. This is a choice that folks might not be intentionally making. If you become aware of this exposure and decide to opt for a an equal-weight index, you aren’t engaging in “active investing”. Quite the opposite.
