they got some funding back, but they view it as a waste of funds to enter expensive team tournaments in which you have zero chance of achieving even a respectable outcome.
makes perfect sense to me.
You're confusing the International/World Championships (Olympics, TUC, Sudirman, etc) with the professional circuit/ World Tour...
It's the professional circuit/ World Tour that you go penny-pinching over about the "returns" since there is no coverage or prize money if you don't get a "respectable outcome"-- VS International/World Championships (Olympics, TUC, Sudirman, etc) which are about diplomacy/ marketing/ representation because you get COVERAGE FROM GROUP STAGE/ROUND ONE.
That's why even when they can't afford or be bothered to send their players to the professional circuit/world tour, smaller countries like SGP won't miss the Olympics, Commonwealth Games, Asian Games, South-east Asian Games if they can help it.
But unfortunately for ENG, they've gone back to what JPN used to do before Park Joo Bong took over (& what SGP is doing now): i.e. just do enough of the professional circuit/World Tour every 4 years to qualify for the Olympics -- wanna guess why it took JPN 37 years to regain the Uber Cup?
IOW, the TUC itself is not "respectable" enough for the ENG sports or Olympic council -- i.e. they've narrowed their funding/focus to only (getting a "respectable outcome" at) the Olympics...
