Yeah, these forks doesn't fix anything, but the people behind these forks try hard to mask their personal gain agenda, by portraying that they are trying to solve a problem that doesn't exist, a hypothetical problem. With Bitcoin Cash it was the increased blocksize. With Bitcoin Gold, it's asic resistant algo to completely decentralize the mining process. Is GPU mining going to be less centralized than the current Bitcoin mining? No.
So in short, these forks are just trying to create money out of thin air, free money and hoping being a Bitcoin fork or marketing it as another Bitcoin they would be able to create a psychological impact on the market to ensure their altcoin gets instant valuation in a competitive crypto market.
,that was what i am wondering also, to think that it is not wiser and could even help bitcoin to its improvement, i don't think so but well i guess maybe its their purpose, while some are taking advantage to this forks they have been waiting for.
