I agree, it's a bad writing practice. And it's very simple to be completely unambiguous - just use the complete phrase the first time. So in this case, the tagline could just be "Decoding Apple's Desperate Ploy To Scuttle Progressive Web Applications", and then, if people see PWA, they can decipher it themselves.

But of course this seems to be a personal blog, so much of it is up to personal taste, as it should be.

I totally agree. For this person, it's surely obvious. They probably didn't expect this to become a popular read on HN.

Do you remember when ai used to stand for 'artificial insemination'? Lol.
