I'd love a longer answer. You seem to be happy to give quips and tidbits, but no substance in your answers.

Great, you've replaced your CRM with Office365 spreadsheet and a documented process in a wiki. Your spreadsheet has history, so audit logs are captured and you can backup. You have a documented and adhered to process for altering data in the spreadsheet.

But depending on your use-case, Salesforce may never have been a good fit. If you're following processes that can actually be adhered to by reading a document to manage your business - your business is extremely mature, well defined and unchanging, has no bad actors (because hitting "Download" on the top-right literally exports all of the company private data) with little compliance requirements, and doesn't require international or external integration, and will never experience unprecedented growth.

If these assumptions are wrong, please share some detail because I'd love to hear about the workflow in your organisation.
