"the dodgy Google/Libre duo"
"There's little that Excel did that I cannot accomplish with one of the dodgy Google/Libre duo"
What's "dodgy" about them? I don't use anything provided by Google except its Translate page, as a matter of principle, but I wasn't aware that people considered it dodgy.
I'm a heavy user of the Libre suite (not Database or Presentation, but only because I don't have any need of them), and find it powerful, reliable and nicer to work with than MS stuff. Given that it doesn't spy on me, steal personal information, runs locally with no need for internet and seamlessly secures my data, I'd say Libre is by many definitions much *less* dodgy than either Office or Google.
