Debian will not ship non-free software in its main repos / official installers. The unofficial images are exactly that, created outside the rules of the project to avoid this prohibition. But, you don't have to trust them. You can download and place the non-free firmware files on a thumbdrive yourself, and the official installer can use them. It will stop and prompt you to insert the thumb drive if it is necessary to complete the installation. https://wiki.debian.org/Firmware https://wiki.debian.org/Firmware If you e.g., netinstall over a wired ethernet connection, it is rarely a problem. But, all 802.11ac and above wifi chipsets require a non-free firmware. You can always add non-free to your sources.list and install nonfree firmware after installation for any devices other than those required for installation, i.e., your network adapter (and in maybe a super rare case for a desktop install, your disk controller).

My first problem with this is the Firmware link you posted. I don't know what to download from it. My second is that I would like to boot from an USB drive first to try Debian 11 for a while without installing it. So there is no installer asking me to insert a thumb drive. I just dd the downloaded ISO to the USB drive.

  Usually missing wifi firmware can be solved without internet this way: - look into dmesg. It will tell you which firmware file is missing. - go (on another machine) to packages.debian.org, enter the filename into "Search the contents of packages" form - download the package and transfer it to the target machine (usb stick, smoke signals, whatever) - either install it as is (dpkg -i) or extract it (dtrx package.deb, then dtrx data.tar.gz), pick that one file and place it to /lib/firmware
