do you have proof of any of that?
the parts that are likely true are that colt subcontracts parts out to various manufacturers. the part that is misleading is that that in any way implies they are the same. it is likely the opposite. even if a given part comes off the same assembly line, if it goes to colt, it may be subjected to expensive testing and QC, that it doesn't get if it goes to a commercial product that doesn't advertise meeting any standard. worse, if a batch of parts is "good enough to shoot safely" but doesn't pass some technicality on the mil spec testing, it may still be sold in the commercial guns.
very few people need an adjustable gas block. but most people do need a gas block that is properly assembled. typically that means pinning it or at a minimum putting a screw into a dimple in the barrel, neither of which are conducive to "scooting". seriously, i hope you're joking.
