I have a question about this specific point. It's true, as you mentioned, that using SegWit addresses helps reduce transaction costs and improve network performance. My question is, why do some exchanges and wallets still use Legacy addresses? I mean, these old addresses have become a burden on the network. So, why aren't they being eliminated? Why do most exchanges still provide users with old addresses?

Can the Bitcoin community pressure these exchanges to prevent them from providing Legacy addresses? I don't mean eliminating existing old addresses, of course, but rather preventing users from being given Legacy addresses and only giving them SegWit or Taproot addresses.
