(...) campaign to direct the technology into a particular untested/risky nonreversible territory.
Where do you get the notion that the changes being discussed are nonreversible? If we can go from 30-odd mb down to 1mb, then I'm pretty sure we could find our way down from 2 if it was deemed necessary.
Alright, I suppose it would be reversible in an emergency situation in which the system is under such severe attack that everyone's coins are in jeopardy. Otherwise, good luck getting miners and others to agree to go back down to 1 MB.
Experience is important but it is not the only factor. If the experienced group doesn't have the right goals, then you end up reaching the wrong ones.
In any case the Core developers are definitely better than those behind Classic.
Yes, better in producing BS and collaborating with Totalitarians.
An example, please, of Core developers "collaborating with Totalitarians"?
