Same here - this quote sums it up quite well:

We built on top of ASP.NET Core because of the option to use it with netfx, and we built things which were intended to last 5-10 years, not for 1 year of support max. This is what the ASP.NET name means in business and it's why large, slow-moving organisations choose it over flavour of the month frameworks.

They should take a look at MS history and look back at the Windows Mobile (6) -> Windows Phone transition for what can happen worst case when you crap all over your enterprise customers.
