He's making stuff up.

Cake offers a convenient way for normies to touch Monero. By default it will connect to clearnet servers for syncing. They ping different Monero nodes wirh your IP (similar to Nostr relays). By knowing which was the last block you asked for you gain a data point, because only 5 people dropped their last connection at block 3,346,263. There are more servers involved e.g. for price in USD (you can deactivate this, but it's on by default). At least one should be able to have ones own price server. Then if you use other wallets (Bitcoin, Ethereum) youbm connect this activity to your clearnet IP. Notice that in this case even your single Tor IP (exit node) would create some data linkage. What you really want is every wallet asking different nodes each time over different circuits including the pings for active nodes. Maybe something like a ping service server makes sense that you trust. Then you only need to create one secure connection to that server and let it connect you to a healthy remote node right away.

Cake offers a convenient way for normies to touch Monero. By default it will connect to their clearnet servers for syncing. They ping different Monero nodes with your IP (similar to Nostr relays). By knowing which was the last block you asked for, you gain a data point, because only 5 people dropped their last connection at block 3,346,263. There are more servers involved e.g. for price display in USD (you can deactivate this, but it's on by default). So if you connectvit to your own node it still will tell someone that you just looked up the price enabling timing correlation. At least one should be able to have ones own price server.

So Cake is not a honeypot right away. Most wallets are lacking those features. Cake is simply by far the biggest wallet, which makes it an easy target. I have nothing against Cake. I use it myself with certain security precautions. But I'd always recommend Feather and GUI for desktop and basically any other mobile wallet over Cake. Simply because their market position will make it hard to get rid of clearnet connection. If they don't take this seriously they will become a bad apple. That's how things are in life. You either advance and improve things or you become the problem. Time dies not stop. Adversaries don't stop either.
