in a segwit HF there wont be any "upstream filter" tier network.
the blocks will just be blocks that everyone recieves.
EG just a upto 4mb block.
not
a 1mb block inside a upto 4mb block that gets stripped to 1mb.
everyone will get the upto 4mb block.
segwit done as a hardfork where everyone is part of the same level playing field peer network.. non of this soft fork tier network crap
This is an outright lie and is far away from reality. Segwit without the base-to-weight ration is not the same proposal that we have today. Such a hard fork can't be called Segwit. The differences between SWSF and SWHF are as follows:
1) Activation (standard hard vs. soft fork).
2) Backwards compatibility (in the case of SWHF, people that do not update are cut off from the network).
In other words, SWHF does not imply a 4 MB block size limit (as opposed to the SWSF 1 MB base && 4 MB weight). It retains the same 1-to-4 ratio that the soft fork variant has.
