I'm confused about this too, I've subscribed to the hashtag #buyeuropean on mastodon and I see posts from this community here over there? 🤔
Have you considered creating new communities for your niche interests? You might just find like-minded people here. :)
The company behind the app is kinda shit though. The German weather service, paid by German taxpayers to collect and provide weather data, has a weather app which used to be free, since it's already paid for by taxes. wetteronline (who by the way happily use the weather data from the German weather service for free for their own app) sued because they thought it's not fair that they have to compete with a better app that's both free and ad-free because, again, taxpayers already pay for the weather service. As result now if you want to use the official weather app provided by the weather service you gotta pay for it, despite already having paid for it in taxes.
All that said, the weather service's app WarnWetter is still the best in my opinion, well worth the 2.50€ that fucking wetteronline forced them to charge for the full version.
OP's a tankie troll who believes buying European is "nationalist", just ignore.
Not suggesting anything of course, but Trump just bought himself a Tesla and if he really really wanted to help Musk improve Tesla's image…
