So there is a group of people that are really against segwit and I don't really understand it. Honestly, I'm not even 100% sure I know what segwit is. Basically my understanding is that it removes the signature part of a transaction so that more transactions can be sent. Also, somehow it allows atomic swapping which is a fancy way of exchanging coins quickly. So why all the hate on segwit?
To my understanding, SegWit is something that "removes the signature" (as you said) to compress the transactions in order to gather more and more transactions by reducing the size of each. Some hate SegWit because even after its implementation, we are still having the scaling issues ongoing as well as the fees are getting higher and higher each day. I think that if they hate it, it's their choice and let us remain quiet and see what they will come up with. For example, those who support BCH will eventually cry because it didn't solve the problem, but increased it by adding 7 MB more to its block size where we already know that after just 7 years, the blockchain size of BTC has bloated to more than 150 GB.
