I think in this case they’re referring to Chrome on iOS. Apple doesn’t allow any browser engine except WebKit on iOS so to many people that means Chrome and any other browser on iOS is really just Safari with a different interface. Pretty sure I saw something recently about the EU considering forcing Apple to allow other engines on iOS.
I have concerns about its long-term effects. I remember around the turn of the millennium using hormone replacement therapy became fairly popular to help women get through menopause while minimizing many of the symptoms of menopause. Then they had to stop it because they realized it was killing a fairly significant number of those women, giving them cancer or something like that.
I personally don’t plan to take anything like that out of concern that we don’t know enough about its long-term effects. I wouldn’t try to prevent anyone else from doing so if they want to, of course; I just think it’s a questionable idea. We get old and die. Trying to fight that seems like trying to fight the ocean: ultimately a losing effort. Of course, I’ve been taking something to regrow my hair for over a decade because I was going bald in my late 20s and felt like that was too young, so I’m not exactly consistent.
