Murena, with their current services, is in no way better than Google.
Honestly you seem to understand the technical side of things but I don't think you fully grasp the economical scale of Google. Murena is literally nobody, like 10 guys in a small shop in Paris, the CEO walking around, few extra staff international, some contributions here and there, it's not symbolic and I don't want to diminish their effort but it's really tiny. Your local supermarket probably has more staff than they do!
Meanwhile... Alphabet who owns Google is nearly ~200k people on payrolls, thousands more outsourced via 3rd party services (e.g. data annotation, social network "cleaning", etc) and the 4th largest corporation in market capital.
Honestly the comparison is not even apple versus orange.
Same for Apple, 3rd market cap, ~150k employees.
Yet... maybe more importantly, Murena has 0 lock-in, none. Meanwhile Apple and Google literally own the mobile market. It's practically impossible to buy a phone without at some point using one of these 2.
So finding imperfections in /e/OS and Murena is fine, again hopefully helping them to grow out of those potential problems, but the comparison ... I don't even know why do it in the first place. Murena literally can not become Google.
