I don't suppose the structural equivalence actually makes sence here. In practice, there is simply no need to block russian social media as no one actually cares about russian social media, beside Russians and people from other CIS countries, like Belarus, Kazakhstan or Ukraine (AFAIK, Ukraine actually blocks quite a lot of large ru-net sites, both social media and news outlets).
It would be an honest comparisson if e.g. Telegram gets more popular in the West and there would be actual temptation to pressure it. We actually already see the first signs of it in Germany, where anti-lockdown protestors are using Telegram and the government doesn't like it.
And remember what had happened to TikTok as soon as it became massively popular? It was forced to surrender and get sold without a second thought.
