It's amazing how fast it is, even for uncached queries. For cached ones, it retrieves results before I can even mentally register that I pressed Enter.

I wouldn't be discouraged by this article.

• Galaxus is an online store that's mainly popular in Switzerland and they only recently started to expand into the EU market. The Swiss can be surprisingly Eurosceptic, so it makes sense that they wouldn't be too interested in any Buy European/Buy from EU movement.
• Although they sell other stuff as well, Galaxus is mainly focused on consumer tech products. The fact is, it has not even been a full year since Trump was elected and nobody is going to suddenly come up with products that rival the likes of iPhone on such notice. Consumers cannot be expected to buy European when there's no viable European alternative.

I wonder why you think so. Some like Peertube & Threema are definitely poor alternatives but I wouldn't say it's "almost all" either.

• Deezer vs Apple Music/Tidal: Deezer has a great selection of music and recommendation algorithm. I've never used Tidal but Deezer is definitely better than Apple Music IMO.
• Tuta/Mailbox.org/Posteo vs Gmail: Well, they all let you send and receive emails. Unless you're an enterprise user, I don't see what advantage Gmail would have over the others.
• HERE WeGo vs Google Maps: Very recently installed HERE and didn't have any issues so far. This can be a bit location-dependent though.
• Ecosia vs Google: Ecosia uses Bing/Google^1^ as its search index anyway, so the results are almost exactly the same for me.
• DeepL Translate vs Google Translate: DeepL has a more limited selection of languages but for the languages it supports, it's the undisputed king.
• Bolt vs Uber: I only used Bolt a few times while I was in Portugal and it seemed fine. Maybe this is also location-dependent.

^1^I think it's Bing by default but you can configure it to use Google in the settings.
