>>10812800Let's count all the reasons...
>monolithic Lego has sheer market presence and brand recognition>widespread mental associations of inferior quality towards non-Lego brands still commonplace>Lego continues to dominate in ease of access and distribution>Lego wages aggressive lawfare against all competition with its preferential status as a "legal" monopoly on plastic building blocks>Lego has been hypocritically hostile towards anything resembling "modern warfare" which pushes those interested in such things to either MOC their own or pursue adjacent hobbies such as plamo>real-world military toys have been trending downwards for some time in general (army men are also in a slump at present)>Cobi is often near or the same price as LegoThere's probably more reasons but those are the most significant ones that come to mind.
