I'll preface my answer to clarify that I'm against surveillance capitalism and privacy Zuckering. I say that in the open, do not use Google services, Amazon, have my own PeerTube instance, IoT at home is HomeAssistant with ZigBee, etc. So my goal here is NOT to cut some slack to anyone.
I started with this because I'm not actually sure what you are referring to. Since my initial comment is about Murena STT I'll assume it's that but if not please correct me. This specific service... is not a compromise I would accept. So I'm in NO way advocating for me. The only thing I'm clarifying is that this service is not something one can "stumble upon" and enable without paying attention. That's why I put such recurring emphasis on it. It's not coherent with "sharing all data" or imagining a scenario where somebody buys an /e/OS phone Murena and somehow ending up getting their data leaked (due to the potentially imperfect anonymization) to OpenAI. One has to activate it and to do so one must be a Murena services paying customer. This is not the case when "just" installing /e/OS. So once again I'm not saying Murena is perfect, not even that it did the right choice (according to my own privacy preferences) my relying on OpenAI, and yet that problem is not relevant to most people who use /e/OS.
To make a quick a analogy it's like installing WhatsApp on a privacy OS phone. Sure you technically can do that but if you do and complain about how Meta is collecting your data then you did it on yourself, you can't blame the OS developers.
