No, they are run by bad businessmen in a highly competitive market who fail to understand that good creative people are rare and need to be respected and paid appropriately. You can get mediocre people anyway to churn out forgettable stuff, aka the Netflix approach, but even when they have proven people they still don't pay them enough. You can't keep a streaming service profitable if 70% of the new product is mediocre at best, people will not keep paying money monthly for a service where they only like 1-2 shows that only air one season a year if that.
There will be a big consolidation coming in the next 10 years, maybe even one of the big ones will be forced to merge with another or several other services, because people are just fed up to have to track at least half a dozen services and hunt for shows that are actually watchable ( and stay around, which is a whole other issue, looking again at you Netflix).
