I don’t doubt this phenomenon exists, but I’d be cautious about ascribing intent or deliberate action to produce it.
Another very real possibility is that degrading quality over time is a natural consequence of the models’ capabilities, usage, and misplaced trust in both.
"Anthropic, OpenAl and Google release their new models with high quality from day one then slowly nerf them until the next model, so when the next model hits, its perceived as a bigger jump than it actually is"
sounds right what's happening
