It’s worth watching, yes. To understand the purpose of CalyxOS, you must understand the purpose of the project, of course. We can’t simply say that it’s a terrible Custom ROM for privacy, as he did. It was quite wrong and in bad faith to say that a project that, yes, is much better than using a Stock ROM, however, the fact that he compared it to other Custom ROMs that also claim to focus on privacy and showed that CalyxOS doesn’t differ much from them is completely valid and truly a fact. DivestOS, with only one developer at the helm, was much more hardened than it. Which makes one wonder why CalyxOS, with an entire team behind it, doesn’t follow the same example. It really is disappointing. Want to prove it? Check out the website (https://eylenburg.github.io/android_comparison.htm) he shows in the video and see for yourself.
Regarding the implementation of GrapheneOS’s Google Play Services sandbox, I particularly like it and if it is to be considered something to popularize the use of open source OS (GrapheneOS), limiting Google’s data collection (since the use of Google Play Services sandbox is completely opt-in), it also maintains compatibility and avoids many issues so as not to alienate the general public from enjoying the other benefits of using an open source OS, something that MicroG does not do, however, I use it and I think it is an incredible project, but take into account the perspective of popularizing open source by the general public without associating it with software issues.
That is why, when I refer to understanding the purpose of the CalyxOS project, I really understand, what I mean is that there is no prospect of changing and becoming a more hardened Custom ROM benefiting its users. A lot of things could be improved. There are resources for that.
NOTE: I know about the end of the Divested Project development, which is worthy of applause for the time of contribution to the community and of thanks without a doubt. I only used it as an example of a truly hardened Custom ROM and that should be the goal for those who say that their OS is suitable for journalists like the CalyxOS team.
