In the least judgemental way possible — consider familiarising yourself with languagetool https://languagetool.org/ (supports many languages; supported by some programs, like LibreOffice), you can self host it or use severs provided by 3rd party or Harper https://github.com/Automattic/harper (currently supports only English; and has very limited support by other programs). Because “de-boogle” is definitely a choice for an typo (ᵕ—ᴗ—)

Boogle Maps:

While maps is important and all that, but do not forget about public transportation. Currently, CoMaps is useless for that, so it is also worth mentioning solutions for public transportation. The biggest open source solution currently is https://transitous.org/ There also list of programs that use this service, like https://github.com/Wafler1/transportia

Note, that in some countries this service might give results that are raging from full to none, compared to Google or other providers.

YouTube * Client:

Still, GrayJay is really good for YouTube (and PeerTube and more), with cool features like local network sync, Harbor for decentralised comments, Linux client, download for videos and stuff that are part of ui (meaning, that you download videos inside of GrayJay), and more.

Boogle messages:

Note, that this does not cover RCS functionality.

Gaming

Worth mentioning Shattered Pixel Dungeon.

Eh, even in context of tech-savvy users it is still questionable. It is not like tech-savvy users do not need to get from place to place in time with public transport or an car, they are just a regular people, just like non savvy folks.

I, for example, could consider myself one (tech savvy), but even I can not deny that this projects and services kind of… stink, and not usable as big corpo solutions.

Do not get me wrong, I am in love with OpenStreetMaps, with Open Food Facts (and related projects like open prices facts), with Mangrove Reviews, and so on, and I contribute when I feel like it, but damn me if there would had been usable programs and UIs for using Transitious service (and especially with fully offline functionality), or program that use Open Food Facts data for anything even remotely useful (I once made feature request to CoMaps about adding open food facts data, so it can be used for searching food and non-food items on map or opening place and scrolling through list of items it has with prices, but this PR was quickly closed as too niche ¯\_(ツ)_/¯ , and then couple months later we have mangrove reviews, which is even more niche and has even less data but hey, what do I know), and for other related projects.

A new project, called “Mangrove Reviews”, has been quietly

Calling it a new project is a bit of an stretch, I would say, considering this project was around for maybe 6 or so years.

Also, for anyone unaware, mangrove is not only for reviews of places, but also websites, books, companies. Found a bad site which scams people? Write an review. Found bad company? Review it.

I wish there were more options, such as videogames, software, food and non food (Open Food Facts can be used for identification, in similar vein that OpenStreetMaps is used for places), and more (and more then 1000 symbols per review in general), but currently we have only that.

Why people don’t wanna switch from Gmaps

I do not want to be that person but I think the main reason is people do not give a fuck about any of that. Or just in general not giving enough fucks for anything.

They have working shit on their devices (in this case — Google Maps), which do what they want and have many features, which varies from “nice to have” to “this is very important to me to the point of not being able to live without this feature”. Traffic data, reviews, and so on.

And when you try to introduce something else to them (especially something as fragmented as open source real life data “stack”, OpenStreetMaps + mangrove reviews + transitious + more) — you would not be meet with enthusiasm, especially if this other service is just worse for one or other reason.

What is the point if they want to input some address in, for example, CoMaps, and they get nothing in return because nobody had added that place and address for 10 years and doing address search is hard? (Both of which Google happened to master to a much higher degree then OpenStreetMaps).

However, navigation services like MapComplete and CoMaps

Calling MapComplete an navigation service is definitely a choice. Or CoMaps for that matter, conspidering that they currently are not providing much of an navigational services for public transport, and that their routing engine sometimes can lead with the most weird paths (but this one is more of an issue with OpenStreetMaps data, which only highlights my previous point).

is this real competition yet?

Right now it is definitely not. Many-many-many places lack even single review which says “good place”, so for the most of time you do not even notice that service.

Godot has succeeded on rivaling other game engines like Unreal or Unity

Eh… Maybe in indie, sure, it might shaked Unity somewhat, but many games still made with Unity and other proprietary engines. Big studios still on Unreal and some even switching from their in-house engines to Unreal, so eh.
