Since your post is in the privacy community, I have to say that I would never ever use any softwares from Microsoft for my own projects, not even open sourced and self-hosted ones. Everyone knows that Microsoft love to collect data and so do Google too, and Clarity uses Google Analytics.

Google Analytics is banned in some countries here in EU only because of the violation of ones privacy.
