No in most cases. Meta products are banned, twitter, discord and youtube (this one mostly works in reality), but pretty much everything else is unaffected.

Some Western side companies banned Russia by IP's like Intel, but in general, my list of websites to tunnel through a VPN is rather short, like a dozen and mostly to unblock youtube as meta and twitter are cancer anyway.

The block is on the Russian side (in most cases), but not all Western sites are blocked (Hacker News is working). Most of Russians know how to use VPNs, though it is extremely inconvenient.
