I'm not especially aware of this particular thing, but sending an SMS with a link to a web page that asks to install a PWA seems to me like it would work on any platform that allows PWAs, irrespective of whether PWAs are restricted to one rendering engine or not, and totally unrelated to the exploit outlined in the post I was responding to (about a somewhat unclear process to me, that would open sites in the background, sending prompts to the user and somehow automatically installing many different PWAs this way).
What we are talking about is specifically targeted at the EU where iOS represents about 30% of users, and doesn't apply to the US. So it's unlikely that scammers would just hold off from exploiting Android and wait for the EU to force iOS to allow different browsers, and only then exploit this class of vulnerability.
That was in response to your statement that “in all those years this year not been a problem on the dominant platform”. It has. The exploit in the news article is only possible because of the way Android lets websites initiate a PWA install, with a prompt that looks like a normal app install, lacking any warning about unsecure sources.
Android was also infamous for causing users to develop permission-blindness and just accept everything, later replaced by every app havinf an extensive permission list that everyone just shrugs and accepts as normal.
