user-1: if the hardware wallet company ledger goes out of business, what will happen to my crypto asset / private keys in ledger? I heard that the hardware wallet ledger is not open-source, so will the company get access to my private key? Will I be able to transfer my crypto elsewhere?

if the hardware wallet company ledger goes out of business, what will happen to my crypto asset / private keys in ledger?

It's difficult to answer about other cryptocurrencies and security of each. This website is for Bitcoin and you should be fine even if hardware wallet company like ledger goes out of business because they don't have access to your private keys, seed and other backup information which can be used to access your bitcoin using open source wallets like Bitcoin Core, Electrum etc.

I heard that the hardware wallet ledger is not open-source, so will the company get access to my private key?

No they don't have access to your keys afaik. There are other hardware wallet options available as well: Coldcard, Trezor, Bitbox, Jade etc.

Will I be able to transfer my crypto elsewhere?

Yes. You should always have multiple backups and keep them safe. They can be used to access your bitcoin. Test your backups regularly to ensure they work when required.

user-1: Your keys are stored securely on the hardware device itself.
If Ledger (or Trezor) goes out of business then their wallet client will also most likely not be supported anymore.
This isn’t that much of an issue. Other wallets have support for interacting with your hardware wallet, like Electrum for BTC, Electron Cash for BCH, and MyEtherWallet’s website for ETH.
If you also have your seed written down, you can import that seed into Electrum. This is more of a last resort move though.
