There are essentially 3 leading fabs left: TSMC, Samsung, Intel.
Samsung has yield issues, Intel has yield issues, TSMC somehow has no issues. GlobalFoundries has already dropped out of the race. TSMC is selling every wafer they make, and continues to invest heavily to solidify it's lead.
ALL of these fabs depend on ASML machines. IIRC last year they delivered just over half of the machines that were ordered.

That would not surprise me at all. I was hired on contract once to help a system (not ICs) that was having issues and my work was directly obstructed (a coworker said sabotaged) by the guy (foreign) who designed one subsystem. At the time I though maybe it was his ego not liking that his boss brought me in to help and I was succeeding. When it became clear from multiple incidents that he was subtly sabotaging me I started to wonder this very thing. I showed evidence to our boss who said "my hands are tied" because of the corporate structure at the time. My work did make it into production and I moved on for other reasons.
But if you'll allow your question to be answered with pure rumortown and supposition:
Intel has engrained management issues that don't allow for reorganizing to systemically address their 10nm and under process issues as the little fiefdoms that control different parts of the process are spending more time throwing each other under the bus rather than collaborating.
Samsung isn't far off from TSMC (about a single node). They fell a little behind as TSMC grabbed a bunch of their contracts (most notably Apple) which left them with not as much to capital to invest in their newer process nodes at a rather critical point. At a bare minimum they'll be kept alive by TSMC's customers as a viable second source (if you squint hard enough) as a negotiating tactic (see Nvidia's 30 series on Samsung as a shot across TSMC's bow).
GloFlo canceled 7nm and under R&D. I wouldn't be surprised if they bounce back at some point when all of the EUV gotcha workarounds are more or less public knowledge and the equipment doesn't have prices on the order of a small country's GDP. If we hit fundamental limits at ~1nm and Moore's law really dies, then they should be able to jump back in with relatively less work than a newcomer and be the budget option once leading edge chips become a commodity.
