Concerned about Google's monopoly and approach to privacy, I've decided to take some steps towards ungoogling my life. Here are some alternatives to Google products:
This is the easiest part but also one of the most difficult ones. If like me you've used Chrome all your life, switching to Firefox may be super hard. Fortunately, there's an alternative. Ungoogled Chromium is a fork of Chrome that removes all the google stuff from chrome. It comes with a downside tho, you'll need to follow a specific procedure to install new extensions.
Use DuckDuckGo. And if those "your data shouldn't be for sale" popups annoy you, use DuckDuckGo StartPage. Missing some results? Prepend
!g to your query and you'll get the same results you'd get with Google.
Google Drive, Docs, Sheets & Slides
For Drive you can use use Dropbox, or Nextcloud if you have a server to host it on. The best alternative I've found for Google Docs is Notion. For slides you can use slides.com, and Airtable is a good alternative to Sheets.
