That's true. I use both mobile wallets like Lumi and Ownr for everyday usage and a hardware wallet for storing huge amounts of crypto.
Is it another newbie alt-account advertising these two malicious closed source wallets? The more these are advertised by these throw away accounts the more confidence I am that they are trying to scam people. Refer to my previous reply:
It's also important to store crypto on non-custodial wallets like Ownr or Lumi.
It is stupid to store anything in closed source wallets since you have no idea what is happening in the background. The best case scenario is that they aren't malicious and you lose your funds due to a bug and worst case scenario is that they are malicious and not only they are monitoring everything you do but also they have all your private keys.
Ownr is completely closed source
Lumi has some libraries on Github but not a proper source code and it is not popular at all
