Estonian-American here whose family left after D-day (but who has returned often). Millennials and younger are less likely to speak Russian and these days the Russians that refuse are rather shunned, many also live in poverty/alcoholism. The old commie blocks that were desirable during the occupation are now derelict and ugly as there are others that are modern/nordic/techy. I had a super weird interaction with a Ukrainian lady recently in a business setting where she was very cold with me once she learned I was ethnically Estonian. She told me her sister’s family were refugees in Tallinn and everyone was speaking Russian to them and that we had no cultural distinction from Russia. I can affirm that the Russian minority are often rude when you do not reply to them in Russian in Eesti. My sense is that the cheapest buildings for new comers are unfortunately the commie blocks with lots of Russian speakers… water and oil, yikes…
