Fees are crazy high right now ; just after halving we had some blocks with multiple BTC from fees. So for now most miners aren't at a loss - if they weren't before halving of course.

Of course when Ordinals shit will slow down, we can expect many small/medium range ASIC farms to switch off, but the said ASICs will be sold and used somewhere else in better conditions to be profitable again.
