You can see their position. The infrastructure isn't cheap to maintain, and if a lot of people move from on-grid to off-grid the costs don't decrease for them, they just have less revenue.

This wouldn't be so bad in places with non-profit power companies, but the for-profit power companies are going to feel some pressure.

Maybe the era of big grids should come to an end.

A neighborhood can share a neighborhood sized grid in a much cheaper way than an utility managing city-sized one. Even more if the only function of the grid is connecting into the nearby big battery and sharing some energy when one of the houses has a problem.
