Oracle was never really innovative on a technical level , it's first and foremost a company focused on selling licenses, and they're really innovative in that regard but if you fall for that as a company, I have no pity, this is their whole schtick.

Big companies in general are often rather conservative in nature while innovation happens on smaller scale and later expands.

The big problem is rather that a lot of innovation has been absorbed by the big companies via buyouts, especially when money was cheap to borrow. Innovation bears risk, buying an established solution and milking existing users much less so.

I don't think the users are without blame. A lot of people ignore the red flags when a solution is just convenient enough (we need the commercial support / this exactly covers our use case so we don't have to hire someone to adapt it / ...) and the vendor then cashes out when moving away from his solution would be really expensive.

I think there's still a lot of innovation lately, but a lot people are just looking for the next big thing that does everything it feels like.
