Take a look around the OW-member airline boards and you'll find that the grumbles are less than few and far between; QF, BA, AA case in point.
While the OW alliance may, at a strategic level, have agreed to prioritise premium pax it is, at the end of the day, an alliance with associated schemes which exist for YOUR benefit.
If you don't agree with what each of the member airlines are doing, by all means blow off some steam on these boards, but also make sure you feed it back to the member airlines. And don't accept a response which begins by "... we realise it must have been immensely disappointing...", we all know how to cut and paste, after all!
