Someone trying to convince others that FOSS alternatives are just as good does sounds just like a vegan trying to convince meat eaters that vegan alternatives are just as good. Sure, in some cases it can be pretty decent, but it’s undeniable that it is similarly “unnecessarily” limiting. Ask main stream users if they prefer photoshop vs gimp, macOS vs Linux, foss video games vs Fortnite/COD/Minecraft, libera chat vs discord, mastodon vs twitter, etc etc.
