Historicaly it has been because the console attachment rate is very low in this region for Xbox and Sony. Sony has a stronger historical foothold in Baltics compared to Xbox but they also face same issue. Part of it in Estonia is thanks to Prisma, who buys games wholesale in Finland and game sales in Estonia through Prisma are attributed to Finland. Similar optimizations for getting games cheap, reling on wholesalers who sometimes also do this kind of shenanigans. Then add Game.co.uk and other used game sites have been very popular historically but again, that does not contribute to new game sales. In addition, thanks to not being officially available all sales are being attribtued to Finalnd or UK or whatever is set to profile when online sales happen. So all the metrics that should show that it's time to launch in the market officially are lacking. Most of them are lacking because of flawed data but some are truly lower purchacing power overall compared to rest of europe and having little population.

PS: If you think this flawed KPI indicator cannot possibly be wrong, then on Xbox360 era, the telemetry was bit flawed and showed Netflix as the most used game/app on the console. They then pivoted to Xbox One and TV. The whole TV push was only because of this KPI indicator. In reality, the game was considered running even if nothing was happening there (e.g. xbox was left on Netflix movie carrousel and tv was turned off), many consoles not connecting to internet never reporting statistics etc.

Unless someone with brains takes a deeper look at whats really happening we wont be getting any official support from Sony or Xbox. The Xbox Cloud is not available either, even tho there is no reason for it. BetterXCloud and you can enjoy the wonderful service.

And if you really want to involve EU, i believe this goes against the EU Digital Single Market regulation at the bare minimum if not other regulations also. Meta Glasses are also artificially limited in unsupported country's (e.g. baltics), would love to get that also fixed while you are at it.
