No I did not invent the term, it is a catchy if somewhat ugly snd crude description of decline in quality, wiki cites
'Enshittification is a pattern in which online products and services decline in quality. Initially, vendors create high-quality offerings to attract users,
Same might be said of Posts, Presidents or shrinklation where pack/bottles seem same but size or quality of content declines.
Of course it may be just I am so old I remember when Mao was a hero on the long March from Ajarn Forum via SubNeroLiam to present state.
Canadian pundit Doctorow cites
"Here is how platforms die: First, they are good to their users; then they abuse their users to make things better for their business customers; finally, they abuse those business customers to claw back all the value for themselves. Then, they die.
I call this enshittification, and it is a seemingly inevitable consequence arising from the combination of the ease of changing how a platform allocates value, combined with the nature of a "two-sided market," where a platform sits between buyers and sellers, hold each hostage to the other, raking off an ever-larger share of the value that passes between them".

We cannot stop progress IMHO I think the world was a better place without Amazon, Ali, Shoppe, Shein, Temu, Facebook , Twitter and Instagram.
