I'd like to mention that most IRL trots don't "hate" MLs - it's recognised that there are in general far more points of agreement than disagreement nowadays. This of course can greatly vary by specific Trotskyist and ML tendencies, but the major exceptions are very fringe.

I use Graphene OS. While you can run it completely de-Googled, in order to run Play Store applications Graphene OS takes the route of sandboxing Google Play services. This means that they run with the privileges of a regular application and you can deny it access to e.g. sensors.

Sandboxed Google Play is practically identical in functionality to its non-sandboxed counterpart from the stock ROM, and nearly all applications should work. I can confirm that WhatsApp works for certain, as well as my banking app.

Calyx OS is another one that uses MicroG as a replacement for Google Play Services instead, but I have not used it.

"Today, five countries exist that can be said to be communist: China, Russia"

Tell me you have no idea what you are talking about without directly telling me you have no idea what you are talking about. In what way can today's Russia "be said to be communist", and how does its current, very explicitly anti-communist government, contribute to the point you are making?

Claiming socialism had "barely any social climb except at the beginning" unlike capitalism is not something that you can do while maintaining any shred of honesty. The reality is objectively the complete opposite. While there are plenty of valid criticisms of the USSR, access to education was not segregated by wealth, top universities were open to all who knew their shit, and throughout its entire history party leaders tended to come from humble backgrounds.

Now, compare the above with the USA.
