Microsoft Finland itself commented on the use of Windows 95 (https://archive.is/7md8S, in Finnish):

"It's fun and great, what else can I say! The performance was absolutely hilarious and we are very happy about it", Pekka Isosomppi, Director of Communications at Microsoft Oy, commented to Iltalehti on Monday morning.

"This is a product that has been dead for quite some time. If you were driving a car from the '50s in a stage show, would you ask Ford if it could be there? The '50s car is part of that era and a symbol of that era – in the same way that Windows 95 is a symbol of the '90s", he argues.
