How do creators of Google Chrome extensions make money?

Question

Google Chrome

There was an idea for a chrome extension, I thought what could be done and published. But time is money, as you know, and I thought: how do the creators of Chrome extensions pay for their time? Of course, you can say that they do it for the benefit of progress, but you also want to eat. But not only that, I still need to pay Google $5, despite the fact that, in fact, I am improving their browser.

Answer 1

The $5 fee was made just to weed out the bots.
Earn, whoever. I saw the trail. ways
- donate
- embed advertising in pages
- PR of someone else's project (referral system)
- PR of your project

Answer 2

If the extension becomes popular, then it can be sold , and the new owners will do not very good things for the user.
