Is it legal to sell Opencart builds?

Question

Licenses for software and other works

Hello!

I have a question about the GNU GPL 3 license. The question is about the OcStore license.

According to the license, this engine is distributed as open source. Anyone can make their own changes. In principle, this is the same Opencart, only with its own improvements, etc.

There is such an assembly as MaxyStore and DigiCMS, which are distributed for money. How correct is this?

It turns out that any user can, based on Opencart, cut his own engine with attribution and sell it on the market?

Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things.

In general, the answer to your question is easily googled
