I too would like to see Qantas report how many long haul business class seats they have released in the past 12 months compared to the same period 5 and then 10 years ago. I would gladly stand corrected if my anecdotal evidence is way off the mark. In fact, Qantas would immediately dispel all the negative comments and prove all the naysayers (including myself) wrong regarding long haul premium Classic Reward seat availability if it did publish the actual figures.
I think people would still complain even if they released this information
To be honest, I suspect it's more than likely the amount of long-haul business seats being released hasn't decreased. It's the growth in QFF members, and probably just as importantly, more and more people being into "point hacking" and actually spending their points on high-value redemptions, such as business seats.
It's hard to have any hard numbers for the latter point, but anecdotally from my friends and colleagues it looks like a lot more people are churning credit cards etc. to get that elusive business class redemption now vs. pre-covid or even before that. Previously people would be members of QFF, but would likely just redeem a few economy flights and/or toasters. And no, it's not me introducing them to this world (I don't talk about it that much), it's them coming across it on social media (e.g. TikTok influencers peddling credit cards) and then coming to me for advice since they know I fly a lot and know the FF programs well.
Of course, the end outcome is the same for us regardless, but it certainly matters for Qantas Loyalty's bottom line. If you're getting a lot more points being purchased by banks for credit cards etc. but aren't increasing availability of your most expensive* redemption (Classic Rewards), then that's an easy path to Loyalty's current growth... well, until people catch on that the availability doesn't match their expectations.
*expensive as in the cost to Qantas Loyalty
As for the original article, I think it would be good to have a section on the general feelings of AFF members towards CR+
