I replaced my Mac's default apps with these free and open source alternatives

When I initially switched from a Windows PC to a Mac, I started using all the default apps on macOS since they were free to use and most of them offered a good set of features. However, as time passed, I started feeling locked in since a lot of the apps are limited to Apple's operating systems and platforms. This started causing compatibility issues with files exported from those apps, and also with the apps themselves, since I use an Android phone, and most of Apple's apps aren't available on the Play Store. Additionally, some default apps like Finder were just too barebones for my liking. That's when I started looking around for alternatives.
