Where do you find their revenue stream data?

They’ve probably never made any money.

"in August 2021, Discord had reported $130 million in 2020 revenues, triple from the prior year, and had an estimated valuation of $15 billion"

There's no evidence in that sentence that they have made a dime.

The company may not have recorded any profit, but the founders and other equity holders can leverage or sell that equity worth $15B.

Revenue is not profit. You need to subtract expenses and whatnot.

That’s right. But for GDPR no one cares about profits. They need to be fined on revenue.

Otherwise non-profit making companies could do any privacy BS and not be fined.

Good point.

They need to be fined based on gross annual worldwide revenue or market cap, whichever is greater.

Fines will go up if they don’t fix it.
