There have been tons of innovation in the field of electrical engineering since the standard voltages and frequencies were fixed. New installations are made to a better standard than older ones, while still maintaining interoperability. They don't blindly stick to the status quo without ever questioning if there's a more cost-efficient option like big-corp IT departments tend to do.
So if you were building a 40-storey high rise office building and the sparky you hired decided to install electrical outlets that were all 400 Volts and 30 Hz, you'd be fine with that?
I think a better analogy would if the sparky decided to use a new type of wire with better conduction than standard copper.
As GP comment said, there has been innovation in the electrical engineering space that maintains backward compatibility.
So if Open/LibreOffice could actual deal well with MS Office formats, for example, whilst removing the annoying bits (cost, telemetery, UI[0]), then yes, it might be wise to move on from the status quo.
[0] in practice I don't think the OpenOffice UI is better than the MS Office, but in theory some people could prefer it
