Kremlin mouth-peaces can express their bullshit worldview outside of the EU, and they do that quite liberally. It's up to society to ignore them, ultimately it's everybodys own decision. But if you come somewhere, spread propaganda while being paid by adversaries, then you aren't welcome. I applaud the EUs sanctioning of these individuals, and I don't really care to hear from pro-russian folks why that's a bad thing in their eyes.
