This is very low on my list of grievances though. I like those vector characters quite a bit more than the stock photos they replace.
Kurzgesagt mentions on its patreon that they used to spend on average 150 hours on each episode and are now at up to 500. While the style stayed mostly the same I think there is now also a lot more going on visually than in the early videos.
While the uncluttered design for something someone only uses a couple times might be fine to avoid overwhelming someone. If you use it daily and even multiple times a day that can make it harder to use.
It also remind me something i read about a ticket kiosk for some transit system. They updated the kiosk with simpler interface to select various things. While effective for infrequent riders, people who would purchase tickets daily found it much slower because the old kiosk allowed them to type in codes they memorized.
If everyone hated this and considered it "corporate," it wouldn't be the one used by some of the animation studios that create the most popular content (e.g. Kurzgesagt).
