Or in other words: We are ready to sell your private data now. Because that's what actually happens when you login to another website via Telegram login.

Yes, this is implicit in what the parent is saying. The point is, your data can be shared if you volunteer it by using this feature.
> Secondly, you see what informations will be shares with the website.
At a minimum, you are sharing the fact that your identity logged into the application. A profile of logins associated with your identity can be built, and a profile of how many Telegram users logged into a particular website can also be built. Both (and particularly the latter) are valuable.
> Lastly, there is no money involved. It's totally free to use.
This has nothing to do with whether or not your data is actually shared or sold with third parties.
I'm not necessarily agreeing with the parent that Telegram is going to start selling user data, but your arguments here do nothing to diminish the fact that they could do so en masse. A graph of your logins should probably be considered "private data."
I don’t follow what you’re arguing. It seems you’re agreeing - yes, Telegram could sell the login data.
The commenter you replied to was expressing a (snarky) hypothesis that Telegram will sell login data. You initially said this was nonsense, but are now saying that they could do so. That’s basically the point.
Here you have the basic info (not ticking additional boxes) people share with the party your're logging into via Facebook login (for privacy reasons I have reset most fields):
First, it's you who decide to use telegram to login to a website (as you would login with Facebook / google).
Secondly, you see what informations will be shares with the website.
Lastly, there is no money involved. It's totally free to use.
