They save them pre-checkin for status holders (people who fly 25,000+ miles a year typically). As someone who flies _way_ above that number I appreciate that they do, as I am typically buying last minute tickets (less than 2 weeks out) that are much more expensive. Those seats mean that despite paying more than most people on the plane, I'm not stuck in a middle seat most of the time.
That benefits attracts people like me to try and stay loyal with an airline rather than going with the lowest bidder. I'm willing to bet that people with similar flying habits to me provide the majority of profit for an airline as well.
I understand what you're saying, but the mileage programs are not really about "loyalty"; they're about misallocating corporate dollars to more expensive seats to the benefit of the airline and the traveller/employee. I don't feel that people like you providing "the majority of revenue" to airlines should really matter either way. Dollars for seats.
I managed to just cross a mileage program threshold this year but I'll continue ranting about how terrible these programs and the flying experience in general is. Especially because having bargain-basement status on United means nothing when you're flying out of a major hub :)
The MCE seats also serve this purpose.

Well, because it encourages people like you to keep their "status," and people without "status" now have to pay extra for a regular seat, it probably benefits the airline. But it is another fare class that the airline invented to make more money, much like the basic economy fares discussed in the article.
My academic institution refuses to pay for any kind of seat upgrades, so from my perspective, the rational response is to fly on another airline. I will probably have to avoid airlines that start "offering" "Basic Economy" fares for the same reason.
