Given that Daredevil is IN this show, as well as Kingpin... not to mention that by most reports, Daredevil has essentially been shot already... I really don't think this is the case.
Now, rumor has it that Feige... hated what he saw of the Daredevil show, so that might possibly play something more of a factor.
I can reserve judgement until the end. Maybe they will do something impressive, like the Daredevil show being something akin to a mini-Defenders type thing, bringing in a few characters from the new mature arm of the MCU.
Not a rumour. In September they let the writers and directors go, brought in new ones and revamped it. Saying "Daredevil has essentially been shot already" shows a gross misunderstanding of, well, everything.
As well, D'Onofrio has stated that story elements from Echo are setting up things in Daredevil. So Echo had to come first, regardless, since also, that's how stories work.
As what was already mentioned, there is a LOT of behind the scenes stuff that go into making anything. Saying "I want this tomorrow" doesn't make it so, not even close.
