is it really that hard to make advanced fully mechanized lenses?
No... the key issue is production cost.
Germany, like Japan, has a very high labour cost. To take the example of Japan, a lot of precision manufacturing that used to be in Japan have been relocated in lower cost Asian countries.
Sony's Zeiss lenses are definitely not made in Germany and Sony never publicly says where the lenses are made, just the phrase that the lenses are made to Zeiss standards.
Even Schneider's B+W filters have different quality versions. There are the more expensive brass ring ones and the newer ones are now made with aluminium (lighter in weight) and are reputedly being manufactured by Hoya and China made.
In a globalized market of OEM manufacturing, this is a common thing nowadays. Zeiss, Leica, Schneider all lend their brand name to lots of products that are certainly not made in Germany.
