Wete they complaining about greater *risk* of orphan blocks rather than an increased *rate* of orphan blocks?
That's not what your linked posts are complaining about. Both pools have an orphan rate of zero. In fact all pools mining sub sat txs have an orphan rate of zero https://x.com/mononautical/status/1968138304265900433

The risk is purely hypothetical. However both pools made *more* money by mining sub sat txs. They certainly didn't *lose* money.
It seems strange to stop doing a profitable thing because of unfounded fear. Do you find their behavior strange?
That's the thing: it is NOT profitable as according to ckpool it increased rewards by 0.06% which is nothing.
