I share your concern, but 'analytics', 'telemetry', 'web beacons' (whatever it's euphemistically called) have been adopted wholesale by developers when creating software. It is rarely questioned by developers because it have become so normal.
An uncomfortable truth is that it is often developers who incorporate user tracking in their software. It doesn't matter if the software is an OS, a desktop app or a SaaS 'cloud' app.
For example, Microsoft's Visual Studio Code is a desktop app that collects telemetry. Electron makes it easy to embed analytics in an app - something developers are eager to do.
Google's ChromeOS is a 'cloud' OS used by millions of school kids in the US. It is not possible to use the full features of the OS without a Google account. Even if user data is 'anonymised' and aggregated we are talking about volumes of data that are simply enormous.
User tracking in software is a juggernaut that shows no sign of slowing down, particulary with the popularity of SaaS. [1]
What do developers have to say about this pervasive tracking?

Developers are more likely to defend their favourite tech company rather than question or scrutinise their tracking practices.
[1] This is a Figma blog post about how Notion was designed using Figma:
"It was around that time we noticed Ivan in Figma. He suddenly popped to the top of our most active user list — spending upwards of 18+ hours a day in our design tool."

The last time this story was posted on HN, the snippet above passed without any comment - and was considered a perfectly normal use of user tracking.
