I guess it depends on what you mean by "much".

YoY 3Q advertising revenue growth was:

- 2019: 28%

- 2020: 22%

- 2021: 17%

Was it going to trend downward to 17% without the iOS change? Who knows.

Where are you getting 17% from? The linked financial highlights show 33% YoY revenue growth for advertising.

I believe that is the income growth rate, not the revenue growth rate.

That is the income (profit) growth rate.
