The fact that a fast track was even considered is controversial IMHO. People flipping out, especially if their retirement is tied up with those indices, is to be expected. No one wants to be a bag holder for billionaire insiders.
You're making a similar mistake treating it as fait accompli that SpaceX will tank between IPO and some future date, but that isn't a given either.
Every rule change is controversial. This one was less so than almost any prior one I can remember–the dual-class one in 2017 (later reversed) generated far more real press. This one was mostly an influencer thing.
