Let me clarify . . .
My female Betta, the Gourami and the ghost shrimp are in a 20gal tank. LOL The little ghost shrimp have plenty of places to hide and they are not bothered.
Only my male Betta is in the 2-gal tank. I would not put Bettas together in any of my tanks. But, I have put male Bettas in community tanks with no trouble. These Bettas mostly kept to themselves and were not aggressive. I know that they can be, but mine were not.
The fact that I feel that fish should not be put in little cubes is my opinion. Of course, you have your opinion and are entitled to it. We do not have to agree. That we disagree is something I'm cool with.
