Bitcoin Cash is at least honest (except perhaps for the confusing name)-- it isn't attempting to force anyone to use it. It trades as its own asset, and you can see that the market (so far) hasn't really wanted what its offering.

Beyond the deceptive name, Bitcoin Cash is at worst an honest difference in views. S2X on the other hand is being promoted with extreme levels of deception and dishonesty (like the content of this article, which states it's an upgrade rather than an incompatible replacement and claims that BU and Classic are compatible full nodes when they aren't any such thing: they don't implement any of the new under-specified S2X rules, ... they don't even implement segwit.)

> about a 2MB

You're not talking about 2MB-- 2MB is the size of blocks with segwit in effect. You're talking about 4 to 8 MB, which are above what prior research indicated was supportable even while considering a subset of considerations (such as initial synchronization), _and_ while not allowing any safety margin.
