I don't think I'd object to the comment if Blender actually had a bad UI, but I don't think it does. It just has an unusual UI and a steep initial learning curve. Clearly many people manage to do amazing work with it.
There's even a three-part article (2013) from Andrew Kramer of Blender Guru, describing the issues and with some suggestions for trying to fix them. Luckily, Blender has made progress since then, and I'm sure we'll continue to see a great piece of software get even more consistent and clear in the future. Note: this doesn't mean dumbing the software down.

It's not a secret that a small, vocal minority of Blender users feel that way. IMHO most of them have never used industry standard tools that have way stranger interfaces eg. Zbrush that are much harder to master.

It was actually Andrew Price:

He later admitted at the 2013 Blender Conference there were a lot of problems with his proposal and that the way he had gone about it wasn't that great either:

Not completely unlike the grandparent poster, which is presumably why he got downvoted.
Blender might be a "nightmare" for you. But without putting any proper criticism, your point is null.
Also as interesting as this new program is, it's not an "alternative" to Blender, it barely scratches the surface.
