I am writing an online web game, I want to monetize it and make it open source at the same time, is this possible?

Question

Monetization

If I make it open source, it is clear that people will start to launch their forks on separate servers, and then it makes sense to monetize the game, it turns out - I created competitors for myself and compete with them myself.
Please do not give an example with the Linux kernel, because Am I lying smarter than Linus :)

Answer 1

Open Source != Free
It is possible for those who will earn on your Open Source project to "impose tribute" ...
What do you want to get from Open Source?
PS read Eric Raymond "Magic_cauldron" maybe there will be recommendations in choosing between manetization and open source

Answer 2

Open Source projects are not monetized, however, the time of its developer is monetized.
If you create an application that will really be in demand and bring irreparable benefits to society, then sooner or later one of your users (the administrators of your application) will contact you with a request to make some specific feature specifically for their installation, or help with installation, or consult in the format of a private conversation... That's what you can take money for.
