How do we know Microsoft and Apple aren't giving our wallet information to the government?

Ive been buying a little bit of bitcoin over the last year using coinbase (since it was the easiest entry point for someone who lives in NY), but now I want to start to stack some non-kyc coin. Been trying to research this and have some questions.

How do we know that platforms that we see our wallet balances on, like using Legder Live on Windows and Iphone, are not linking our wallets to us and sending that information to the government. We know Microsoft is notorious for giving up our personal info, what's stopping Windows from seeing Electrum installed and seeing the public key ( I know the private key is held on cold storage and is safe) in the wallet and sending that information out? How do we know this isnt happening?

How do we know the same thing isnt happening when we use Bisq? cant Windows track the activity on the app, and link that activity to the cold storage address that we then send that "non-kyc" bitcoin too?

Also side question here, just bought a Trezor model One to store my non-kyc btc, whats the best software to use with it (Electrum, Trezor suite, ect)?
