why do people dislike The Family reunion so much?

i've seen this pop up several times as one of the lore critiques of V5 and tbh i just don't get it? the whole point is that the Giovanni grew so cancerously insular that they couldn't maintain their independance unless they were willing to come to the bargaining table with the other necromancers and let the surviving Cappadocians back in. like isn't the fact that they're a phantom clan clinging together despite violent internal discord the whole point?
