Do you know the number of projects in the space implementing sharding, many of them. The thing here is that many of these projects start throwing around big jargon around and you find out they are not better than the present technology, there is still reason why Ethereum is still leading the Dapps market despite all its well know shortcomings and no new project come close to it
Maybe those new developers didn't know properly about what's the real purpose of hardfork. As far as i know, there were more than 10 projects were selling sharding as their jargon to compete with ethereum or try to replace it but they didn't know even sharding can be implemented easily through create an EIP that will be voted by the network. What they were doing to sell the jargon to get the hype. This mostly happened to the new project when it offers better features than the existing platform but all BS.
