Which license to choose for commercial software?

Question

Copyright

I wrote a chat script, I want to sell it, but I'm interested in the issue of protection against piracy.
It would be easiest for me to deliver the code to clients in a completely open form, and to protect against piracy, use a commercial license for the code + a symbolic license check in the code that even a schoolboy could cut out.
Who wants to spirit even a protected product, but for conscientious clients and me, first of all, working with uncustomized code will greatly simplify the support and distribution of a software product.
I would like to choose some kind of typical simple, short and understandable commercial license that restricts the rights to distribute and sell the original product and products derived from it, and so that in which case it would be possible to sue those who use pirated versions of the product.

Answer 1

licenses are about open source.
closed code is proprietary.
And everything is determined by the contract / patent.

Answer 2

> Which license to choose for commercial software?
Free or non-free - neither one nor the other contradicts the concept of "commercial". However, based on the text below, you want to make your program proprietary.
It's sad, but I can't help you within the given limits, not so much because, but because there is nothing - there is (thank God) such a pool of ready-to-use generic licenses for non-free software that exists for pro-free software.
Each small proprietorschik, as usual, either writes a license himself, peeping at a neighbor, or turns to a professional. The second, of course, is preferable - since you are ready to collect money, be prepared to pay yourself. But there is nothing complicated in the first one either - there is no need to prohibit a lot of intelligence.
