If you're collaborating with other people (with some narrow exceptions), the idea of sending around point-in-time snapshots of documents feels horrifying. And, to your point, LibreOffice is from an era when providing a plausible alternative to Microsoft desktop products was a big deal. It really isn't at this point. Mainstream users use cloud-based options and specific power users use Microsoft Office.

The idea that Google has every startup’s term sheet, plans, budgets, is really strange to me. USA can so easily spy on every other country’s data.

Am I the last dinosaur? Are all the other concerns dead?

No, you are not. This is truely strange.

I can understand giving away grocery lists to the world, but not this.

I mean, at Google scale the investors in global capital all know each other and invest in each other’s funds anyway.

And most customer lists are on Salesforce. ADP has everyone's salary data. At the end of the day, the safe thing is to just disconnect all your computers from the internet. But that's not very practical so you decide how much of your company's time and energy you want to devote to reducing potential security exposure while your competitors are just taking advantage of available online services (with some level of security due diligence).

Fortunately you can work on shared cloud documents while still having more features and the faster response of local applications. I often work with local Excel or Powerpoint apps on cloud documents while another colleague is working on the same document. If I need to share the document, I just add someone to the share list. If someone emails me a document to work on I switch it to a cloud document and then share it back to them to try to change their habits of sending out discrete copies of documents.
