 Compressed music uses algorithms to save space.  It’s never a bit for bit copy.  Absolute sound has done many articles showing that a ripped file in flac is not bit for bit.

 

Do you have a reference for that claim (issue, article name, page number, etc.)? If lossless compression did not expand to exact bit-for-bit copies of the original information, then the Internet wouldn't work. Neither would your computer.

Agreed.  The internet (aka the cloud) and your computer would not work if lossless compression did not return bit-perfect results.  Almost everything you access on the internet (Amazon, bank statements, brokerage accounts, Apple, utility companies, this website) is stored on devices that use lossless compression.  Google even invented their own lossless compression method and made it open-source - see Google Snappy.  The only resource lossless compression requires is CPU horsepower which is plentiful in modern computers.

 

For long term archiving, choose whatever lossless format is most convenient for your needs - ALAC, FLAC doesn't matter - and don't lose any sleep over it.
