I do use PipePipe, but I recommend NewPipe since the former is merely a fork that cannot survive without the latter.

The few people who really care about me, agreed to contact me via SMS.
The close family even uses XMPP for me.

It is not related.

The money refunded to Nintendo, comes from the govenment, paid by the citizens’ taxes.

A lot of programs and services I use are not present so I did not include those alternatives.
Of those I included, I use only a few, too. These are sane alternatives for the common user.

Not everyone uses a powerful smartphone.
«Works for me» is seldom a good advice. OsmAnd is perfect on my Google Pixel 4a (2020), but can’t run decently on my father’s Sony Xperia L3 (2019).

Florisboard also exists, which has more features than e.g. Fossify.

I use Unexpected Keyboard because it lets me write in many different languages with the same layout, and I don’t have to go on an expedition to find a special glyph.

It invalidates the point of GrapheneOS. The latter supports only Google Pixel for a reason, which is security.
On unsupported devices, you should stick to LineageOS.
