I must agree, you are right, GOS is only on Pixel phones.
But we have to keep in mind that /e/ has a lot of problems, the only one solved is sending data to Google. The security aspect of the OS is problematic and some key elements of a privacy seem questioning (AI integration, commercial collaborations, ...).
Uploading speech-to-text to OpenAI? Regular communication with Google? Using Google for assisted GPS? Giving a bunch of Google apps privileged access (if you need them for e.g. Android Auto)?
Well and besides that only shipping ASBs and no other security updates outside major Android releases (and both usually late). Using heavily outdated kernel trees (e.g. FP4 is using a Linux kernel patch level that hasn't been updated since 2020!), outdated vendor firmware blobs, etc.
It might work, but it is not very secure, nor very private.
The OS is working well, but have privacy and security concerns.
Is it better than a stock OS? I don't know, maybe, maybe not, it depends on the stock OS.
Reading the links posted in a sibling thread it only does it if you have text to speech enabled and they use an anonymizing proxy so openai can't associate sessions with any particular user ie it's not perfectly anonymous and private but I don't see how you could have totally anonymous and private until you have a fully offline on-device TTS model, which the fairphone guy said they tried and didn't feel it was up to scratch.
I don't use e/os but it doesnt' seem like a terrible compromise to me personally.
