Completely invalid argument.
How many times, over the years, did CCP completely rehaul nullsec to incentivize decentralization… to make all regions of space, or even individual systems interesting to be in? Equinox does exactly that, for example.
Now see if you can find expansions which are doing that for highsec - making all empires interesting to be in. The last significant effort I can remember were Epic Arcs (a feature available once every 3 months) and COSMOS… which was introduced when… in Red Moon Rising or something (can’t exactly remember stuff which was more than 10 or 15 years ago).
