The key here is Intel is expanding the idea of operating their fab for an external customer (foundry services). What they’re doing with specific fabs or processes is less important relative to their bigger emphasis on working for a client like Apple.
In some areas they may be shifting resources. But a lot has happened since last summer. They have received some cash infusions and 18a is in full production with yields, apparently, at acceptable levels. Rumors are Apple has already signed on.
New CEO said he'll continue with Foundry provided he gets significant customers to justify the cost. In a recent comment/press release, Intel said they are continuing production on 14A. Ergo, they have external customers (or Trump is bullying him into it, but I suspect it's mostly the former).
