Even if it's nice for people who want just this, I don't think this has its place on the annoyances lists you mentioned.
Annoyances are mainly for things like cookie popup or copy-protection etc. I doubt companies would argue these are their "core features".
Before IT took away all plugins (!) I used uBlock this way, hiding sidebars and leads that weren't conducive to work (eg interesting stuff).
weird decision, I push plugins to lots of my customers (uBlock Origin)
They really like dealing with users and their malware infections I guess. It's the only possible explanation given that uBlock Origin is probably the most effective anti-malware software in existence.
