Yes, I noticed the "have a discussion with us" bit to the letter - which may or may not have been a platitude. It may have even been an opportunity for the (ex)member to feel appreciated or there's an option, or even for QF to say look we'll give you X status as you actually flew Y prior to covid as compensation or a good will gesture etc. For many who do fly and earn their own no real change. It seems unlikely QF would change their minds based on a phone call, but possibly an opportunity for the member to vent with a human - or maybe in a rare instance of a stuff up say "Well actually I'm now the manager of corporate travel for [ASX 200 firm] ....' and QF could reassess.
As a few have pointed out about CL was never a FF status per se and its granting was never based on an level one could earn so to me the notion of a "soft landing" is not really relevant. By the same token comparing with Plats Golds etc wanting status extensions is a bit of Apples and Lemons for mine. In the case of a FF member who had earned status but could not hold it due to reasons beyond their control - covid, borders, and all the rest where they likely would have continued some sort of pattern of flying then sure, extensions or StatusKeeper is appropriate (and QF has done all this, like just about every other loyalty program). CL is a totally different beast though because membership is not earned in the same manner.
I imagine QF sees this time as a good one to "cull the herd" as it were because they may have had numbers of hangers on that they knew had moved on, or they did not deem to be as valuable as corporate travel influencers etc as they once were...
Whenever I am given something I didn't earn or pay for etc by a company or even a friend, I don't automatically expect it to continue (even things like the P1 Christmas Gift - should that return in the future). I accept it as is and every renewal is valued.
And of course the majority of CL's who have been sent these letters (obviously this may only be a small number of people - we don't really know) may not be angry and may be accepting of it (and again during these times a perk they can't use when there are so many other real world issues to worry about ) and move on. This could really just be a disgruntled few who reached out to the media.. a bit like those celebrities caught out by the dress policy at the QP (remember those heady days?!

) and coughing on insta.
