Because Monero IS a centralized hard forking shitcoin that makes people poor, you can have private transactions using Bitcoin, obviously I am not against privacy Lightning, whirlpool, joinmarket, ecash, paynym, take your pick Additionally many people who use Monero don't run nodes and broadcast their transactions without realizing their privacy is compromised by using someone else's node or swapping their BTC for Monero on compromised exchange, it's only "good" at privacy under perfect conditions, might as well spend that same effort to use Bitcoin privately
