Mandatory Telemetry

In recent years, more and more software/websites use "mandatory" telemetry.
What is mandatory about it? Well, I don't know. So does no one else, I asked, if people who are working as software developers or the CEO of a company I worked for.
It seems like no one knows what is mandatory about it or why it is needed.

Well, I can tell you what they want. Your data.
As seen in the screenshot above, from Silent Hill F a single-player game which apparently needs some telemetry to work. I call bullshit on that.
There is no reason that they need any kind of data to see if the game works on a console. (The screenshot was taken on the PS5)

Even games like Minecraft "need" telemetry now. Those are not just for server use, no, they also want those data for your single player worlds. Why?
Over the past few months, I heard things like:
I can't put swear words on signs anymore
or
I can't talk about adult topics on my private server with other adults.

There is no reason for any of that; they only want control over it because they can.
I would understand if for public servers (where it's still on the admin/moderators).
Older games used to have crash reports, so if something went wrong with the game, a window would open up, where you could describe the issue you had and send it off to the company that made the game (or the publisher, whoever wanted the data you sent them then). They even asked for permission on what data to collect in those reports.

The only reason for cookies and telemetry should be
1. Websites where you buy things, so you don't lose the cart while browsing the site.
2. Online games, to make sure no one cheats and to ensure the game works as intended.

Places where we should not have any telemetry:
1. The operating system you are using (Windows / MacOS / Android / IOS)
2. Single-player games
3. Regular websites that you just visit for the fun of it (advertisers should not be allowed to track you anyway)

(Might add something later)
