Could these laws be used to go after people who download free GNU/
Linux-based OSes such as Ubuntu and then burn then to CDs and hand
them out for free?

Excerpt:

The difference is that this time, the anti-piracy laws were enacted at
the behest of the US trade representative, who made stringent patent
and copyright enforcement a condition of the recent US-Russia free
trade agreement, forcing Russia to take on board stricter laws than
those in place in the US. This includes laws that would never pass
Constitutional muster stateside, like a scheme for police licensing
and inspection of CD and DVD presses. Imagine that: Russia reinstates
state control over the press at the behest of the US government! The
Framers of the Constitution would be very proud, I'm sure.
