Optech's news section is particularly excellent this week, kind of required reading (topics are LN eclipse attacks and the segwit double signing attack on hardware wallets - warning there is a *lot* of nuance in this topic, but they break it down better than I've seen anywhere else):

I would be heart broken if other hardware wallet fix this like Trezor did. I spent lots of time coding hardware wallet support on BTCPay Server (and the BTCPay Server Vault).

We will have to stop supporting hardware wallets completely depending on how vendors behave. :( twitter.com/BtcpayServer/statu

Alice sends tx A->B but the coins actually end up in Z. Then when normie Carol sends a tx an analyst must deal with possibility that Carol's coins disappeared too

In light of the BlockFi personal information hack, remember how its this same company who ban users from protecting their own privacy with CoinJoin.
There's nothing in regulations saying CoinJoin must be banned, these guys have just drunk the Chainalysis koolaid. twitter.com/BlockFiZac/status/

Lockdowns prevent many people from earning a living, but the politicians, bureaucrats, and police officers who create or enforce such restrictions are all earning their regular paychecks. Seems like an incentive misalignment.
