Copyright itself is government interfering with the rights for people to do certain things which are in themselves harmless. What IS unfair is carving out the law to benefit a specific charity.

Bitlocker encrypts when the feature is enabled, not when the computer is "turned on". Every read and write requires encryption/decryption of the data. It doesn't "exponentially" increase the computing power required, modern CPUs have AES acceleration: https://en.wikipedia.org/wiki/BitLocker

You appear to be talking nonsense.

Apple will definitely be concerned about physical server theft, yes. Virtually all modern cloud platforms use encryption at rest to protect against this.

It means the data is unreadable if you have access to the servers directly, eg. by stealing them physically, or by a low-level hack getting access to the filesystem. I don't know if Apple need the keys for any routine access, but they will be stored and handled separately and likely very securely.

Wearing light coloured clothes doesn't work. People will still say "oh so you have lots of cats then?"
