All these things have happened already.

But you are right, they will only get worse.

I was an editor in the industry until I got out in 2013. Going back to my entry-level job in 1996, it got harder and harder each year to “protect” our authors from the creeping consolidation zombies. Middle management was incentivized to clear a path for corporatization — and they did an admirable job selling us all out: Authors, editors, staff, and vendors. The fish rots from the head, as the expression goes. The rot permeated the whole ecosystem, now the smell of mildew has all but overpowered that clean creativity scent.
