At the point where nearly all non-miners want to enable a feature but a few miners are blocking this change, it makes sense for the users to not relay new blocks that prevent the change.
Chinese Miners already agreed to a blocksize increase up to 8 Megabyte.
BTC core is the one refusing to update the blocksize and
are instead trying to force everyone to accept segwit & LN, an OFFCHAIN version (which is no better than using a bank.)
They just wanted more profits so thats why they declined to the increase of 8 megabytes blockzise. Probably btc core has internal links with segwit, LN and offchain versions. I just dont understand why they wanted to make bitcoins more complicated, if it is possible to just increased the blocksize to 8 mb without resorting to other measures then its the best choice.
