Apparently it’s more common than I realized. Most games doing it apparently don’t tell you it’s happening. For example I played RE4 when it was new and had no idea it had dynamic difficulty.
Sony has always been pretty anti consumer. I’m addition to the root kit thing, they have a history of pushing their own propietary crap as open standards. Sometimes successfully (blu ray) and sometimes not (memory stick). They also removed the “other OS” (Linux) option from the PS3 midway through the console’s life cycle.
I’m sure there’s more examples, but they’ve been a bottom tier brand for a long time due to this for me.
