Can we use "ensheetification" to describe this phenomeon? (sure I'm not the first to use this word)
Yeah, I love this :)
What does it imply that the other term does not? Enshitification is the inevitable result of the tendency of profit to revert to zero. This is basic schumpeter (not to mention marx).
I think the other replies are missing your 'sheet' pun, from my knowledge and a quick search, I think you coined it
