I just paid a bunch of Muun invoices from different wallets. The largest fee was 7 sats ( from Lnbits wallet to Muun)  rest are 1-4 sats.   I don't know what are you talking about.

Interesting. You have screenshots?

For Phoenix, I know the channel opening fee can be high (min 3000 sats). But after that?

Also, this is about fees of people sending _to_ Muun. As a Muun user, I don't think you'll notice.

Muun is fee siphoning attacking any sender to Muun wallet

FUD. I use Muun everyday. It's an awesome wallet. You can say it's not a true LN wallet as they use Submarine swap in background. It just woks and the fees are way less than Phoenix and Breez in  my experience .
