Nobody should be using XMR on a closed-source wallet anyway. Doesn't that kind of defeat the point of XMR's privacy if a wallet software can simply collect your transaction metadata and phone home? In fact, I would be more surprised if they were not doing that.
There are more reputable wallets to use anyway, such as Feather Wallet, Cake Wallet, and Monero's official wallet software.
Given the use case of monero as a privacy coin, I don't understand why anyone would use anything other than the official wallet running a full node. Yeah, you have to download the blockchain, host your own node, open ports for remote RPC access, harden the opened ports against intrusion, so on and so forth (or use Umbrel,) but that's the point. That's the only way to ensure your privacy, and if done right, your anonymity, which is what's great about Monero.
Even if you're using an open-source light wallet, but still connecting to someone else's node remotely, there are traces of your activity that you don't own or control. Monero's official wallet can be used to connect to a remote node as well, essentially making it a light client. The only alternative that kind of makes sense is Feather because we're all so used to Electrum, but even that isn't a good enough reason for me and I have no use for the integrated instant exchanges. I do my exchanges through Bisq.
I run three monero nodes; one on my main PC for use as my main wallet, a daemon on my primary node server (accessible remotely,) and another on my Umbrel node just because why not. I have Monerujo installed on my phone, and I connect it to my own node when on the go.
Now that Umbrel can host an accessible and hardened Monero node, there's really no excuse not to be hosting your own. And if you do host your own node, even the official wallet can be used as a light client, and it's aa very good wallet.
