You are making a mistake in equating several things here. Not only is this SpaceX IPO that has latched itself onto pensions through accelerated inclusion in the S&P100 and other funds a different and rather unique matter, but excluding harmful industries is really rather stupid of people who oppose those industries.
If, e.g., all those who opposed those industries had instead bought the industry stock, the people with those ideals opposed to those industries could have at the very least profited from the sale of the stock...which the company itself basically does not see direct benefit from (you are not buying the stock from the company or giving the company any money in most case)...and used/committed that money to even greater opposition. If a catalytic number of those had formed, they could have also even made real impact through shareholder initiatives and actions demanding changes by pressuring board members who rely on votes, etc.
It's one of those nonsensical, moralistic and ...sorry... foolish mindsets that common people have, the idea that simply by not participating the King will leave them be. The psychopathic narcissists in control will never leave you be, no matter how much you virtue signal by not buying their stock from someone else that is not the company or no matter how much you ask or how far you run and beg and ask to be left alone.
Frankly, although I am not certain that it was done intentionally, if I were a major mover and more powerful person, I would propose the very kind of moralizing, self-righteous campaign that has shot the commoners in their feet by getting them to simply check out and not participate in things the could have otherwise controlled a lot more.
So instead of people who actually care...but are clearly rather foolish...all/a disproportionate amount of control and power and money is left to those who do not have those qualms. Hence why none of this "excluding harmful industries" has affected anything whatsoever and we now have square mile measured AI data centers and tens of millions of low climate impact people being moved into high climate impact countries, and we have more war and death and addiction than humanity has seen in 90 years.
In case it is not yet clear to some of us, a stock is like if you went to some second hand/thrift store and bought a brand of clothing that was reviled for some reason or another, i.e., use of child sex slave labor, you giving a thrift store money to wear the second hand clothing not only does not benefit the reviled company, but just alone wearing second hand clothing will likely have more a positive impact than guying some other company's clothing that will later turn out to have used regular child labor.
