Also, the functioning of your hardware wallet isn't dependent on this corporations still existing. There is various free and open source software that lets you manage your hardware wallet, and even combine them to make multi-sig wallets (https://github.com/cryptoadvance/specter-desktop) . This lets you access all information via your own Bitcoin node, no third party system required, fully decentralized.

(A) Link it to your own Bitcoin Core node. You will need a little indexer called Electrum Private Server. https://github.com/chris-belcher/electrum-personal-server/releases . Once you do that, you won't have to ask any other Bitcoin node for transaction history or to broadcast your transactions. You become your own bank, literally.

Electrum Personal server v0.2.4 (Released: 16th June 2022) - https://github.com/chris-belcher/electrum-personal-server/releases

If you want to give Electrum Personal Server a go, here: https://github.com/chris-belcher/electrum-personal-server. It should work fine with Tezor's software AFAIK.

You need Electrum PERSONAL Server, not Electrum Server. Big difference!

To gain some privacy by using Electrum you should set up Tor on Network preferences or by installing your own Electrum server via Electrum Personal Server, ElectrumX or Electrs.
