You have to consider that mining has traditionally been gently and benignly disregarded by most of the media interest in crypto. This is not an accident, the miners are very aware that calling attention to themselves would reveal exactly how suspiciously the valuations in crypto are constructed, and they've done a fantastic job of deflecting attention (with enormous help from the unbelievably clownish behavior of certain exchange operators) and acting like the adults in the fun house.
Serious scrutiny of how exactly the hash rate in Bitcoin is generated would not reflect well on the ecosystem, because of the amount of outright corruption involved, as well as theft, that goes back a decade. A couple years ago an operation was uncovered in Thailand where something on the order of 100 million dollars worth of mining equipment had been found burning stolen electricity from government enterprises, IIRC primarily public schools, and one of the investigators involved speculated that this was likely less than 10% of the illegal mining that was happening in their country, let alone the recognized legal stuff.
Consider that similar things are happening all over the world, not just Thailand, and even entire countries (DPRK) participating due to total systemic corruption crossed with no questiins asked access to natural resources and national treasuries, to be spent in any way they choose, and an investment in destabilizing the world economy - or at least evading financial controls - is well worth the cost of subsidizing mining both within their borders and beyond. You've also got quasi crackpots in charge of places like the government of El Salvador who are also helping to support this ecosystem.
Miners, I will conjecture without offering any support on the bet that eventually this will be found out and publicized, have been sitting on a warchest of nearly free coins mined long ago, when almost nobody was looking for corruption or theft of resources, and when block rewards were multiples higher to boot. The argument that miners have barely made a profit because of the adjustable difficulty level has always been an open lie due to a willingness to completely disregard the mining done using off market access to electricity and facilities, which was rampant in the early days and is still a significant chunk of the hash rate even today.
Miners can continue to slow sell their coin bases because they have effectively paid for them for over a decade at a massive discount to "market," and since the only major source of downward price pressure are the miners themselves, they can prop the price up for as long as they like by simply selling fewer coins into the market whenever there is an adverse social signal that they need to counter with a " honey badger of money doesn't care" price signal.
