Chief executive Abi Tierney has said on numerous occasions that the WRU was committed to retaining all four regions, and while it has not said it will now cut one, it has not ruled out the possibility.
“It’s just another sad day and another sad story in Welsh rugby,” Thomas told BBC Radio Wales Breakfast.
“We need to understand, it’s not just about rugby.”
Thomas said the demise of Celtic Warriors was far reaching and had a huge impact on Bridgend, Pontypridd and its surrounding areas.
“It’s not just about livelihoods of the rugby players, it’s about the town itself, it’s about the area, the region they live in,” he said.
“When regional rugby was taken away from Celtic Warriors, shops closed.
“People weren’t inspired anymore, children didn’t want to play, so there’s a real other narrative that I feel is a little bit more important than the fate of Welsh rugby, and that’s the state of inspiration for towns, for cities, for regions.
“It’s really sad that there’s the potential that this is going to happen again.”
