Many companies already pay for Google Workspace so Google Drive is included.
And for personal use, it's much cheaper than Dropbox.
I pay R$6.99/month for 100GB of Google storage (most of which is used by Google Photos), while Dropbox costs R$10/month for 50GB of storage and doesn't integrate very well with Google Photos.
Not to be glib, but this episode is a little reminder of why that's not always the case. Priceless data now lost (if it is in fact conclusively/irreoverably lost) demonstrates that sometimes in life, its the free or cheap things that end up costing us the most :(
Like why not Dropbox or Sync?
