So far, I’m only using cost-free alternatives:
Gmail -> web.de
Android/Google Play -> LineageOS/FDroid
Google Search -> DDG/Qwant/Ecosia
Google Maps -> Openstreetmap/Organic Maps
Windows/Office -> Linux/LibreOffice
Netflix -> 🏴☠️streaming sites
Spotify -> internet radio/digitizing CDs bought directly from the band at concerts
The only service I haven’t replaced is YouTube (AdBlocked without account), which I use a lot, also for music. And I don’t see an alternative for it either.
Nebula instead of Youtube ($36/year), Kagi instead of Google search ($10/month), Soundcloud instead of Spotify (12/month), Bear instead of Apple Notes (35/year if I remember correctly). And I’ll probably move my email over to Proton at some point and start paying for that.
