Both Supercell and Wolt have their headquarters steadily in Finland. The founders and Finnish early investors have gained hundreds of millions or billions of euros wealth for themselves which they have further spended and invested in Finland. They have paid huge amounts of taxes and keep on doing all of these since they are still located in Finland. It's hard to downplay the value of those IMO. Overall Rovio wasn't a complete disaster either. First made billions of euros for many years and was later sold to Sega for >$700 million. Still has HQ in Finland.
There's plenty of interesting and fast growing startups still left here. For example Supermetrics, Varjo, Smartly, Iceye, Aiven to name a few. IMO you are being pessimistic.
In any case, I agree in that the acquisition is great news and the economy is in a depression. :) Huge part of it is because Finnish mortgages are mostly straight tied to Euribor unlike in other Euro countries and since post covid the interest rates went up, Finns got f*cked. Hopefully the Euribor interest rate will be going down and the mortgages will start to become smaller, at least when they are being paid off.
