This! In my case, connecting to enterprise's walled gardens, such as an Outlook Exchange server or Skype for Business, etc. typically don't have out-of-the-box solutions for consumers on linux.

2 apps I paid for are those for which I couldn't really find a nice/free alternative: 1. Hiri https://www.hiri.com/ as I couldn't find a nice email client to work with Outlook Exchange 2. https://tel.red/linux.php Skype for Business client for linux

I think this category of apps have something going for them. I have since moved to WSL2 though and have found it to be a nice compromise for even serious work.
