If every Russian can see what an inconvenience it is to have Putin as a leader the hope is that they will be more inclined to do everything in their power to have him replaced. Some will of course just blame "west", but there will also be those who will come to question power.
Or, as happened in Iraq and Afghanistan, these actions could further radicalize an entire population.
I think it is safe to assume that if the west applies broad and indiscriminate sanctions that devastate the lives of everyday Russians, many/most are more likely to blame the west who directly imposed the sanctions rather than their own government who will very likely use propaganda to convince them to hate their western oppressors.
It is similar, in my opinion, to the broader Islamic radicalization that occurred after 9/11 when the US employed extraordinary rendition and enhanced interrogation techniques rather indiscriminately on both known terrorists and suspects captured without charge or due process/fair-trial.
Have you considered the risk that these actions could strengthen Putin’s grip on power and provide justification to the Russian people to escalate conflict further?
I gleaned this hypothesis From a recent Joe Rohan Podcast episode with Maajid Awaz, a former Islamic radical, who turned away from radical Islam and helped educate western leaders how to de-radicalize extremists after 9/11. [0]
It certainly applies political pressure with respect to the current war, but it seems absurd to suggest that Russian citizens will replace Putin because of inconveniences on the internet.
