I'd get it if they were meant to be cross platform apps, but they're not. Crazy they couldn't have bothered to write native windows apps in .NET/C# for something that's obviously meant to be Windows exclusive. The community writes way better Windows apps (Sumatra, Notepad++, etc) than Microsoft does internally.
Microsoft has no cohesive product vision for the OS and just seems to let various groups slap random low quality shit to the OS, based on some internal power struggles their managers win in the org I assume. It's ironic that low quality slop like those and ads ship by default with the OS, but the truly useful and high quality utilities they write like PowerToys, do not.
They lost the plot on their core audience after Windows 7 and sloppy implementations of "AI" like Copilot+ and Recall won't bring them back, on the contrary, it convinces people to GTFO to Linux ASAP.
