Here are a few things off the top:

- horrible optimization

    - video calls will easily bloat 1-3gb of ram

- buggy, things that should work sometimes don't

    - e.g. sometimes you click to write... you get a spinner, wait 10 seconds

- poor ux. I have been using it for 4+ years at work, still have trouble finding things

- yeah, all things in one interface

These are opinions. People can have different. To me, its just a slow and difficult to navigate mess that doesn't know what it wants to be.

ClickUp is known to be extremely slow and buggy, in a way that technical people can infer is a reflection of their mission to literally do everything an organization needs.

Who ever built a piece of quality software by setting out to build multiple otherwise unrelated pieces of software with extremely tight coupling to satisfy enterprise bargain hunting?

we evaluated them in 2023, because we wanted to move off JIRA, and their name came up, and we did the initial import, and I spent some time trying to understand what's where and how, and the whole experience was lame. it was aggressively confidently pushing its own features (always be upselling!) but the basics were just not there. It's like Microsoft.

We moved to Linear, which is 2 years younger than ClickUp, but it's solid in what it offers.
