If people watched the video, he actually ripped them out since he was replacing both the CPU and GPU block with better ones from Optimus (and who are also reportedly replacing EK as a possible build sponsor) AND cleaning translucent fluid gunk out of his reservoirs and radiators (and the rest of the loop), which necessitated tearing down the whole thing and redoing it all regardless. And since he opted for an almost blackout build, including new all-black hard-tubing, he opted to just do bends instead of reusing the fittings for joints.
I get Jay isn't everyone's favorite YTuber (and even I disagree with some of his takes), but in this instance, he already stated that he's one of those directly affected with a long-overdue IOU from EK and sooner or later he was going to drop them as a sponsor and minimize showcasing their products beyond only using them as-needed (in his words, their fittings, which he still likes, but doesn't agree with the pricing). I don't blame him, being owed in the 6 figure range and still not seeing the payments even after cutting the final owed amount in half is definitely worth ending a business relationship over, esp. when newer sponsors step up to fill in the gap (reportedly, Optimus and Barrow; the literal extreme high-end and extreme budget end).
