From Creative Commons FAQ:

We recommend against using Creative Commons licenses for software. Instead, we strongly encourage you to use one of the very good software licenses which are already available. We recommend considering licenses listed as free by the Free Software Foundation and listed as “open source” by the Open Source Initiative.

Unlike software-specific licenses, CC licenses do not contain specific terms about the distribution of source code, which is often important to ensuring the free reuse and modifiability of software. Many software licenses also address patent rights, which are important to software but may not be applicable to other copyrightable works. Additionally, our licenses are currently not compatible with the major software licenses, so it would be difficult to integrate CC-licensed work with other free software. Existing software licenses were designed specifically for use with software and offer a similar set of rights to the Creative Commons licenses.

Version 4.0 of CC’s Attribution-ShareAlike (BY-SA) license is one-way compatible with the GNU General Public License version 3.0 (GPLv3). This compatibility mechanism is designed for situations in which content is integrated into software code in a way that makes it difficult or impossible to distinguish the two. There are special considerations required before using this compatibility mechanism. Read more about it here.

Also, the CC0 Public Domain Dedication is GPL-compatible and acceptable for software. For details, see the relevant CC0 FAQ entry.

While we recommend against using a CC license on software itself, CC licenses may be used for software documentation, as well as for separate artistic elements such as game art or music.

I wrote “by osm supporting companies”. The companies behind overture are also supporting osm, that’s what I wanted to write, it’s not necessarily a competitive project, simply data quality is different, but there is an overlap between supporting companies.

Overture maps is a project by osm supporting companies to present their fake and/or low quality data to their shareholders. They can’t import it to osm because of the aformentiones reasons, so they created their own osm with blackjack and hookers.

Roads and landuse data is from osm so it it’s the same. Building contours based on osm and from some MS ai tool, similar to what you get in the RapId editor. At some places it’s good, in dense cities it’s unusable, and there are a lot of false positives, fake buildings on lakes and rivers, etc. Shops and POIs are from Facebook, a lot of them are at the wrong position or they not exist anymore, duplicates and jokes etc.

So as I see, it’s not usable by itself for anything. But it’s license is compatible to osm, so you can freely copy from there. I used it to check validity of osm notes. Facebook via this allowed us to copy data from any page, it was a grey area before. Here where I live a lot of shops don’t have a website only a FB page, and it wasn’t clear if you can copy phone numbers, email addresses from there. Now the same data is available in overture

It was not just a “leak” this was literally on their website a year ago: https://arstechnica.com/gadgets/2023/12/no-a-marketing-firm-isnt-tapping-your-device-to-hear-private-conversations/

Marketing people bullshitting to get investor money. Anyone can imagine non existent technology and lie on the internet, you don’t have to believe everything

(I reread ops question and I can only see the term open source 2 times, but whatever, I understand what you say, and I don’t want to debate about semantics.)

The point with microG is it’s still the best way if you want to use android. The other options are:

• Play services (GMS), or Huawei has some similar solution because of US trade embragoes.
• You can use android without play services but notifications won’t work for most apps, even if you can open them. (UnifiedPush tries to solve notification part) Wifi and cell based location won’t work
• I see microG as an acceptable middle ground. I still have to give up something to goog, but it’s not much compared to GMS, and I can use all available apps

OP asked about Open Source not about privacy.

MicroG minimises connections to google servers, here you can read what addresses it still connects to and why: https://github.com/microg/GmsCore/wiki/Google-Network-Connections

MicroG works really well

A free-as-in-freedom re-implementation of Google’s proprietary Android user space apps and libraries.

Redmis usually have a good 3rd party rom support, if you can open the bootloader. Literally any rom is a better experience than MIUI or whatever they call that nowadays.

There is already a crdroid official available: https://xdaforums.com/f/xiaomi-redmi-note-13-pro-5g-poco-x6-5g.12860/

They collect location of their users but anonimize every data on device, they can’t track anyone personally. They also sell their SDK to businesses and collect data from there as well.
