Anecdote, but, my workstation is Linux, my work laptop is macOS, my personal computer is Windows where I run Linux VMs. I run 1Password across all these operating systems. Having a consistent interface is nice and it means I don't have to relearn the UI three times.

I think many people here will have a similar setup but that isn't representative of the general population or probably even 1Password's client base.

I feel like you didn't read my comment if that's your take away.
