- GMail (webui and apps), Hangout (webui&app), Drive, ... skyrocketing their weight in Mb and cpu cycles without addin really anything new in the last few years. Only if we read "changelogs" on Play store there is nearly anytime "bugfix and improvements" so nothing that can justify such size change. Only data mining probably changed.
- What all users I talk about and me want from a communication service is communication and convergence, so decision to separate SMS from hangout, to have a separate app on Android for Hangout calls etc are simply anti-users features I do not know why are created.
- Allo/Duo seems more an experiment to test their users stupidity/reaction, mine was deinstall them the same day I install few days after first availability announcement.
- I know Google is changed recently with the disastrous new direction, but I remark that Google in the past was NOT a philanthropic geek project and it have made big money on users data as it make today, only real change I see is that in the past such "data spill" was recompensed by good and effective services, now services or disappear or remain the same and became pachydermic.
Long story short: dear Alphabet, you are NOT our "alphabet" nor something we can't live without. Personally I discover many new and nice things leaving your services apart. So I think in the near future you will start to loose users and begin suffer "IBM syndrome"/"bureaucratic syndrome" to the last level, seeing your size you probably do not die quickly but certainly you start to loose profit.
Super short version: stupidity has increased super-rapidly but not so rapidly, not at a live someone want.
