Do you think this can happen to other software wallets ? Especially Electrum ?
Government can not take down Electrum because Electrum is only a wallet and not centralized in any way than its users using central server to connect to the blockchain.
In short, Electrum is not aiming for money in a centralized way that can make government to take it down. It is not even a mixer. Not having anything that can make it to be the government target.
Additionally, electrum is open source.
Anyone can take the code and run, and keep the development
Samourai was basically a software and a service , electrum is just an open software
