> I take the opportunity to let people know that there are alternatives to Google/Apple duopoly on mobile.

In my country (which will AFAIK be one of the first ones to get the new app install restrictions), so far I haven't found any.

You're not allowed to import phones which are not certified by ANATEL, and AFAIK all currently sold certified phones are either Android (from several hardware brands), Apple, and feature phones.

> To me it's like being back when there was only Windows and Macs as viable home computer OS, and people were getting their feet wet with Linux and all its flavours. Now, it's the same but for mobile.

There's one VERY IMPORTANT distinction: back then, you could easily take a Windows or Mac computer and install Linux in it. For mobile, it's never been that easy; strong cryptographic signing of the operating system, combined with endless churn of the hardware design (there's no "PC compatible" equivalent for phones), and there being no way to keep the data partition intact when installing a custom ROM, make it much harder for people to "get their feet wet" with alternative operating systems.
