I guess this has made users of this wallet unsecured.
People who used Samourai didn't lose their funds, if that is what you think or mean. It is a self custodial wallet, and even if they can no longer access their funds in the Samourai software, they can use their seed phrase and import their wallet into another recommended software in order to access their funds. Electrum is not a privacy solution and it is not a target of the government.
Exactly, it doesn't affect the Bitcoin that you have as long as you have control over it.
The reason is that our Bitcoins are stored on the Bitcoin blockchain, not within the wallet itself. As long as you have your private keys or seed phrase that you can access, you're safe, you can still access your Bitcoins using alternative wallet software, even if Electrum or Samuari wallets were banned.
Speaking of Electrum, IMO, it's impossible to be banned, they aren't the same as Samurai.
