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.
