Those of UEFA and Google are silly, symbolic sanctions. What the EU and US are doing is trying to tank Russia's economy and seize/block the oligarchs' properties. Whether that works is left to be seen, but there are already large protests against the war, there might be more protests against the harsh economic conditions, and Putin cannot just arrest everyone.
But in any case, the whole point is that sanctions are unfair, as they will hit plenty of people that are not involved in the war in any way and do not support it. "We" use them because "we" believe that they work (I hope so, but you might be right of course, I'm no expert), not out of spite for a whole population.
I was using a personal anecdote what happens when some foreigners sanction "our" nation, so I used UEFA as an example. It's a similar mentality when it comes to other kinds of sanctions waged against "our" nation.
>not out of spite for a whole population
You may see it that way, but you and average Russian were consuming different media up to this point, and if we admit or not, media has an enormous influence on our worldview.
