Re: "legalized the import of products without the authorization of the trademark holder"
Back in the days of the Cold War the Western countries imposed similar tech embargo on the Soviet Union known as CoCom, meaning you couldn't export stuff such as a Commodore 64 beyond the Iron Curtain. But with many technologies the embargo was two-sided on an ideaological basis. The communist party deemed it evil to use gadgets made by the capitalist pigs, thus even if you somehow managed to smuggle a computer across the border without the Western customs noticing, the local police could still confiscate it from you.
Trade control details are a bit complicated, but the message they want to send with this rule is something like this: You don't have to be afraid of suffering any repercussions from the Russian state if you keep using Western tech, it's only the West that forbids you from doing so simply because you are a Russian, so you should be mad at them, not us.
That alone doesn't mean that Russia would encourage theft, it's up to you how you acquire the products as long as the theft itself doesn't take place on Russian soil. Though basically all of the post-Soviet states on the Russian borders are known to be cooperating in creative ways. For example after the first wave of credit card bans by Mastercard and VISA, people flocked to Kazakhstan and Uzbekistan by the thousands to open a local bank account and get a new card with it.
