After buying a license, Bitrix issues an open source code. What prevents you from copying it and using it on several domains?

Question

1C-Bitrix

Interested in how it is implemented programmatically.

Answer 1

Nothing but the law. There, protection is more of a legal nature than a physical one.

Answer 2

How do you think it is implemented?
There is a license server that knows everything about licenses. The site also stores information about your license. The condition is checked if the license is active - get updates.
There are hacked Bitrix, without the ability to install updates

Answer 3

nothing prevents
funny small web offices can even dump and sell Bitrix to the customer as licensed

Answer 4

I read somewhere that installation and usage information is sent to the company. As a result, licenses may be revoked.
