Wow, so why don’t you complain to your goverment that if you earn $1,000,000 they take $300,000?
There are services that allow making apps without coding that actually take 50%, and nobody blames them, AFAIK
Also, why don’t you complain to Google that if you earn $1,000,000, you only get $680,000? Because, “officially”, you only see that amount, without knowing what they actually take in background
And then substract from that income the “Invalid Traffic” percentage
