There was a recent reveal in court documents where Apple tried together with Adobe to make it work but Adobe couldn't pull it off. Now, I think the point about Apple not being interested in PWAs still stands but I think this kind of thinking is rather new at Apple and ever increasing since Tim Cook took over (Other, better examples of this line of thinking are imo, the omission of critical accessories, the ridiculous upselling in all product families and the increasing intrusion of Apple ads in the OS).
