Honestly that is just human nature, humans just don´t like to adjust to new things ans want to keep everything as they are used to.
Although I have to say, many things of the new UI are just objectively worse, if you need more steps to achieve the same thing you need to justify with some gains elsewhere, like getting a simpler less cluttered UI.
But the new UI is actually worse in all ends, some things are hidden behind several steps, and instead of making it simpler and less cluttered in the front it actually is way cluttered and so big you can not even recognize everything at first glance, so in the end we got it worse on all ends.
