What loss? If they bought the ASICs / GPUs long enough ago they are paid for many times over. Even if you bought only a year before the merge if you had cheap enough power you were under 300 days for RoI on most ASICs and about the same for GPUs.
GPUs can and are still being sold off, and as of now it looks to be more profitable running current or 1 gen out SHA ASICs then GPUs.
As for the other coins that can be mined with the ETH ASICs, it's a tough call. If you RoI already on them whatever you sell them off for is profit. Or, you can keep mining at a loss at the moment and hope those coins go up enough.
Businesses for the most part, if they know they can make money mining BTC but *may* make money mining something else but *will* make money selling the ASICs are going to sell the ASICs and mine BTC. That's just good business.

As of sept 2022 i still had some of my 1080ti hybrid cards mining eth.
they paid for themselves maybe four fold.
IE. 4x700=2800 in dec 2017 made over 8000 with them.
I pulled the rig and turned on an old l3+
I have many old idle pieces of gear i hold them and fire them up when the bull runs.
But now with the looming mega crash not sure what i will do next.
