Spreadsheets are a fundamentally important tool—the original "killer app" for personal computers such as cellphones, and the best way that has been found so far to put computational power in the hands of end-users. Last I checked, there was no spreadsheet in F-Droid, largely because it's a relatively small ecosystem, and most Android users still aren't using F-Droid. Instead they are subjected to the outrageously abusive apps that fill the Play Store, as described for example in https://news.ycombinator.com/item?id=45411897. And many Android phones ship with non-uninstallable malware and shovelware. Backing up an Android phone without a Google account—indeed, even activating an Android phone without a Goolge account—is challenging. From my point of view, these are imperfections.
