Yes! Bitcoin (the BTC chain) got it's GitHub repo hijacked years ago by corporate interests and the company Blockstream. The whole concept is a dead end and they are actively trying to push people into using their "second layer" solutions to the congestion and problems they have introduced.
People like Greg Maxwell and Adam Back were able to kick out the original maintainers and are hell bent on making Bitcoin not work.
Bitcoin Cash is the closest thing to "Bitcoin" now but Blockstream employees an army of Twitter and Reddit trolls to block any real discussion. Greg is basically a one-man-army himself at this point.
I just checked... it's about three to four years post-fork, and the size of the "Bitcoin" blockchain (as you call it) is (minus indexes) about 315 Gb. The size of the Bitcoin Cash blockchain is roughly 170Gb.
I don't know what it was when they forked, but it should have been the same size.
The people you accuse of hijacking Bitcoin seem to have a much higher transaction rate since the fork than the Bitcoin Cash team has achieved.
