Yes you are right, affordability and availability. However because Munich is a hub for Lufthansa as well as Frankfurt, I expect them to update their scanners soon, if not have already done so.
Just found, regarding Munich, as of April 2025
" In October 2022, reconstruction work then started on the central security checkpoint in Terminal 2. In addition to the now completed regular lanes, two further security lanes with CT scanners will be built by the end of 2025, which will offer greater convenience, especially to families with small children and air travelers with limited mobility. The planned conversion measures for Terminal 1 will be completed by the beginning of the 2026 summer vacation period. With the new scanners, the airport, as a premium hub, is thus taking a decisive step towards innovative modernization. "
