Forget bigblockers. To stick one’s head n the sand with that type of thinking is to cede the field to altcoins, in the manner of
Yup. 100kB or bust. Then onward to 10kB. After that, zero transaction blocks are only a short step away and no transactions = 100% SOV security.
Oh gawd richie...
Getting excited about block size is so 2017, and sure I will grant you, perhaps 2018.....
but hey, you gotta do what you gotta do.... while you are not activating our real good buddy... and you know the one.

I'm not going to argue for bigger blocks right now though. I think the need is going to become ever more self evident. Indeed, the recent hashrate crash would have been largely a non-even if there was adequate capacity.
Yes.. this will be interesting to see how these matters play out, for sure.
Tentatively, I am personally considering the playing around with the hashrate last week to end up being a BIG ASS nothing burger - even though it surely had some testing effects on the system.. but gosh did not seem to be sustainable... in other words, better throw some more withdrawal of the mining before it even will start to matter.. try to sustain it for a few months (if there is such a will to stay away from mining king daddy for that long without actually losing out to other miners who end up coming on line), then maybe we might need to start paying attention...
I will agree with you Richy, that the direction of such hashrate strikes has not been resolved yet, so it will be interesting to see if it happens again (you seem to be presuming that it will) and then if it does what kind of effect it ends up having, overall, whether during a price rise period or during a correction (or used as an excuse to make the correction seem to be based on fundamentals rather than folks dicking around and trying to attack our little fiend, aka king daddy bitcoin)... again.. tentatively thinking it is a nothing burger except for peeps who get scared easily and for peeps who want to spread some bullshit narrative about bitcoin being broken.. blah blah blah
