Is there a reason why people are still complaining about Nintendo supposedly "Not making new IPs"?

Nintendo makes a lot of new IPs relatively frequently. The problem is the amount of them that stay. The last new big IP Nintendo made was Splatoon. Arms might become a staple of the company, but it's too early to tell, and I haven't heard that much about it for a while now.

Nintendo was involved in development and invested in Astral Chain.  Does that not count because they had Platinum develope it despite Nintendo owning the IP?
