I dont know, I wouldn't recommend using Facebook or Instagram as backup, and even services like Microsofts One drive have been known to dissapear files. A 'dumb' WebDAV service makes it easy to move data in and out, enabling hedging. Or a company like Backblaze, which has no other monetisation scheme and thus no interest other than keeping your bits safe.
I think you can make much better choices than FAANG or a random company, and I advise anyone to go with that better choice.
