Depends in how clean your room is. I have a case without dust filters and it's been running for over a year without any visible dust accumulating.

Also it's mounted up high, the further you can get from your floor the cleaner it'll be.

You don't really need any airflow there. The only thing that gets hot there is memory, but that is already cooled through the PCB (good heat conductor because of the copper), which is cooled by the regular heat sink.

free libre open source software.

Basically software by the people for the people controlled and kept in check by the people.

what kind of prof is that?

or they're just doing tax evasion, which is way more likely.

A lot oft ROMs allow you go completely disable Internet access for a certain app. Disabling the data collection toggles in GBoard and disabling internet access for GBoard, Play Services, Play Store and the Google App should prevent most logging.

Almost all Linuxes are really private. Because of your ethics and morals, I would probably switch to Debian or Arch, and use Flatpak where possible to prevent apps from spying on one another and reading files from other apps or your system.

Kicksecure, Whonix, Tails, Qubes, ... exist but they're not needed and to much of a hassle for day to day use for most people.

Somehow they might got a special version of the app. Really really unlikely though, it's probably just A/B testing or false logs.

While we all hate reddit, them changing the app icon to make a reference to what used to be a fun event shouldn't be our main point.

According to Exodus Privacy (they analize mobile apps for trackers), Ally only contains Amazon and Google trackers (Google Firebase Analytics is used by almost all apps): https://reports.exodus-privacy.eu.org/en/reports/com.ally.MobileBanking/latest/

Others also say their Ally app doesn't connect to Facebook. Maybe you have a Unicorn or a modified app (rather unlikely though)?

I'm German myself, and luckily I haven't heard "polen" so far (Edit: Might be because I live next to France not Poland). But a lot of my classmates make a lot of kinda racist jokes about the AfD (right, potentially extremist political party) and I can't tell whether they're actually racist or not.

Some children Songs I could never sing vor hear again, they make me cringe a lot (racism, sexism, ...)
