Overall, everything works pretty well for me (user for multiple years), except all apps which are too bound too Google Play Services as microG is not stubbing/implementing all APIs.

So all apps with premium subscription you can only handle through in-app purchase, usually won't work.

I've heard that some banking apps are not working correctly either as not "secured" enough device, in my personal experience, they all worked, it's really a case-by-case logics here.

For the upgrade, OTA upgrade around every month, and it has always worked smoothly

Something I have been wondering with Flatpak is about Ram usage. As sharing dynamic libraries allow loading it into RAM only once, while if I use Signal, Chromium and different others Flatpaks, all libs will be loaded multiple times (often with their own version). So maybe disk is cheap but RAM may be more limited, which looks kind of a limit in the generalization of this method of distribution. (You could tell me it's the same with containers)

Am I right to think that? Has someone measured that difference on their workstation?

Instinctively I would say, to have a direct authentication/authorization process you couldn't have if the client was communicating directly with a MQ.

Is there any plan for a European presence? (At least, for the storage part)

Interesting not really, someone in my family made some research about its past and return to the XVIIth century. From there, we can only make assumptions.

Currently, we are running multiple containers from different apps on the same host. These containers are running with unprivileged users and reduced capabilities but in the same network. It will probably change in the future for a higher level of isolation.

Remind me "The Three Stigmata of Palmer Eldritch" from Philip K. Dick. Selected (clever) people are sent as settlers on Mars, but everybody know it's crappy as hell and that people are surviving thanks to drugs which allow them to remind theirselves what Earth's like. People try to get crazy on Earth to fail tests and avoid being sent there.
