I'd agree with this. Out of Apple/Google/Microsoft, Apple is the one that makes most of it's money selling you hardware, vs selling your data.

I wouldn't trust any of them, but from a security standpoint OSX and iOS seem to be the best locked down under the hood.

Linux is probably the option with the most potential for security, but it's also possible to setup a system that is NOT secure. Something like a Pinebook or Pinephone is extremely interesting from a security perspective, but that is one hell of a rabbit hole to go down if you aren't already steeped in that world.
