Adam Back initally joined Bitcoin with the goal to make it more private. He added confidential transactions to the liquid side chain, hoping it would encourage majnnet adoption. This has not happened. The majority of Bitcoiners don't care about privacy. They won't endorse or adopt any privacy solutions on the base layer. When Developers like Samourai and TDev try to use Client side solutions to improve privacy, they get nothing but hate from Bitcoin Core and are eventually arrested pending trial by the US Government.
