> because of economic pressures

Self-hosting isn't relevant here anyway. When discussing the hoovering up of information irrespective of licences to produce the model, where the model is finally run isn't significant.

You might not be paying the industry pirates-at-scale to run a model on their hardware, but you are still using the same information, irrespective of the same desires of its creators, the same way, just in a different location.

Heck, local hosting might even be making the situation worse if people are trying to train their own model because they are then likely to be scraping data too, and becoming part of the army of bots that are pushing hosting costs up and forcing everyone to use tricks like PoW scripts that can inconvenience human readers as much as the scrapers.
