Google taking 30% of in-app sales?

Question

Mobile development

I want to make my own mobile application for android and ios. Just now I found out that Google takes 30% of sales within the application. That is, I created an application, I develop it, inside the application I sold paid services, say, for 100 thousand, and Google will take and take 30 thousand for itself? For what ?
Are there any alternatives to not paying 30% of income to Google?
It turns out that I generally give 30% of the company's income just for nothing?

Answer 1

Figase.
Google gave you the Play Market so that others can download your shit.
If you don't like it, spread it yourself. You just have zero chance.
30% is generally a gift. It was necessary to take 90% of Google

Answer 2

The state will also have to give
100 thousand income
30 Google
--------
70
- 13 personal income tax (13%, but of the total amount, and not of 70 that came to your account, plus take into account the dollar exchange rate since they were transferred to you on the date of payment)
if IP, then 6 (but whether or not you earned somewhere on average 30 a year, give it to the budget)
there are 57 or 34
left from the second 100 thousand a year
57 or 64
total
114/98
300 respectively 171 and
162
