The sellers are but one part of the larger market system at large.

If SLC NAND went extinct, that's because both the sellers and the buyers (read: customers, aka end users) didn't see value in reliability as much as other factors like storage density and price-per-bit.

You, as someone who does want reliability above all else, are an outlier.

It's more likely because the buyers have been persuaded by the marketing and attempts at deception. When 10k MLC (2-bit cells) came out, offering only twice the capacity of SLC for 1/10th the endurance of the 100k SLC that was the norm at the time, they already had to keep SLC prices artifically high (>2x) to attempt to force people to MLC, and I remember the beginning of efforts to hide the poor endurance. Old NAND datasheets proudly proclaimed their 100k or even 10k cycle endurance. Now it's basically impossible to find a TLC or QLC NAND datasheet that isn't behind an NDA or the rare few that get leaked, and even those which you can find, are extremely vague about endurance. Some parts will let you choose between SLC/MLC/TLC mode for each block, and some SSDs use this for some stupid "cache" feature, but the behaviour of that is not easily configurable --- i.e. without hacking the firmware.

Many PC enthusiasts also want reliability.

TLC cells have about 1k endurance, and QLCs have about 250~500, if the listed TBW figures are correct.

I think this is somewhat misdirected because most end users don't know to think about reliability. When the storage fails, "the computer broke", they take it in somewhere and the tech gives them a fixed system with the data gone but had the CPU burned out, they would be just as accepting for the data to be gone in that case too with a "sorry couldn't save it".

The marketing might include a x-million r/w cycles in it, but it's going to be way under presented vs the speed.

That simply reaffirms customers don't care about reliabilty as they do the price tag.

They would if they were aware.
